Matt caused Celeste to commit suicide by telling Juan about his relationship with her.

I would love it if the killer was Valant, trying to get Trucy the death sentence for what she did, but that's more of a Last case idea...

In Kurain, there's about to be an arranged marriage between Maya and another man from another Channeling group.
Pearl is distraught, and says she's willing to do anything to stop it, so she goes to help from Iris, and somehow they get tied in with Morgan's branch of the family, and she's planning to kill Maya, so that the Main family branch doesn't continue.
Pearl may ask Iris to channel Morgan, so that she can talk to her as a daughter, Iris accepts, as long as Pearl locks the door, Iris channels Morgan, and before Pearl can lock the door, she pushes her aside, and runs through the Kurain house.
Pearl is spotted by Maya's husband in Maya and his room, she can't tell him what's happened, but tells him not to open the door to anyone.
Morgan, still in Iris's body, comes up with a plan, she dresses as Maya, and tries to find Pearl, once she does, Pearl takes her to her room, and tells her to wait in there until Pearl says it's okay to come out.
While Morgan can't find Maya, she's still locked in the same room as her fiance, she grabs a knife and attacks him, he defends himself with a kurain statue, he hits Iris over the head, knocking her unconscious, when this happened, Morgan left her body and Maya's fiance had to channel her, while Morgan was in his body, she took the knife from Iris and stabbed herself. Pearl was still looking for Morgan, when she found Maya, realizing she had brought Morgan into Maya's room, she ran back with Maya, who found Iris and her fiance on the ground, she fainted in shock. Somehow, Pearl didn't manage to go in with her.
Pearl ran back to her own room to channel Morgan, after locking the door, so that she wouldn't be able to cause any harm, Morgan has to come up with a way to make it look like a murder. (Note: Part of the wedding outfit the fiance was wearing had gloves, so there are no fingerprints on the knife. She manages to get (Witness 2) to unlock the door for her, pretending to be Pearl, and ran down to Maya's room, putting the knife in Maya's hand. The worst happens, and Iris wakes up, Morgan lies on the ground, pretending to be Pearl, Iris looks at the scene, then goes out to call the police, while this is happening, Morgan leaves Pearl's body.
I don't know weather you'd play as Apollo or Phoenix, though.

Winston Payne is arrested for suspicion of golfer Albert Ross (Go on, guess the pun). Payne was at the scene of the crime playing a private game with the victim during the night, and the victim was beaten to death with a golf club with Payne and the victim's fingerprints on it, though the golf club had preserved its shape.

His daughter asks for the defense request, because Payne's shocking(ly beautiful) is out on tour performing in an opera. During the investigation, you meet Payne's golfing apprentice, an ex-wrestler (let's call him John Fore). While Payne is friendly to John, he secretly wants to faze him out, but can't because he knows he'll be crushed in his rage. John is quite clingy to Payne, but is also a little slow. Think Lennie from Of Mice and Men. John admires Payne as a very skilled mentor and great person, and usually stands up for Payne whenever someone makes fun of him.

The first witness is the janitor of the golf club, who claims two people broke in, and one of them was Payne, who was seen scampering to the bathroom. After being vocally assaulted by Apollo's chords of steel, he reveals that he was paid to let them golf, and didn't see the person, only Payne's golfing equipment on their back.

John Fore starts to show his short temper, so Apollo takes this as a lead and investigates his background. He meets with John's old wrestling manager, who tells him that John Fore, or by his wrestling persona, "The Foreman", grew obsessed with another wrestler, and after being betrayed for a title shot, beat him half to death. It was kept a secret from the police and media, and John was forced to retire, under the cover of a heart attack risk while doing a demanding sport.

John Fore's the second witness, and he's exposed as having a grudge against Albert Ross, for always making fun of Payne and bringing him down too often. That night, Albert taunted Payne throughout the entire game, and Payne yelled at him and went to the bathroom in frustration. John followed the two to the course that night, and when Payne left, he went up to Albert and protected his honour. Albert, the cocky bastard that he is, picked up Payne's golf club and waved it in John's face, while badmouthing him further. John, absolutely enraged, used his own golf club and beat Albert to death, taking that club with him.

John Fore is arrested, Payne is acquitted and no longer trapped via his clingy apprentice. Happy ending.

The police were called due to neighbour's concerns over screams and sobbing coming from a house. Apparently, a man was murdered in his apartment, found next to his body at the time of death was a frantic woman covered in his blood and holding the murder weapon, which was covered in hers and the victim's fingerprints. She was sobbing hysterically and what she was talking about was incomprehensible. Phoenix reads this information in the paper and sees the picture of the defendant... was that the assisstant from his "simulation"? No information is known about this girl at all, her DNA was not found anywhere in the criminal records. Phoenix thinks he is going insane, but no matter how he looks at it... it's her. Phoenix urges Apollo to take this case, Apollo, bewildered about Phoenix's persistence, ends up taking the case, finding that he faintly recalls seeing the woman also. The woman is distraught, upon first meeting she is still rambing about things no one quite understands. Trucy is able to get her to think straight and the woman becomes sane again, with Trucy's help, she returns to a cheery and happy personality, but as soon as someone begins to mention the murder, she becomes hysterical. Apollo and Trucy realise that they would not be able to get any information from the case from her and continue the case without her, only coming back to ask her about certain people, but nothing (as far as they know) pertaining the incident. The first day, Apollo and Trucy try to figure about as much as possible about what occurred that day, but to no avail. In court, the prosecutor (Fran 2.0 I guess) takes the erratic behaviour of the defendant into account and use that as a point to the defendant's guilt. Apparently, the defendant also recently began to faint at random times and soon wake up. One of the witnesses is a psychologist who agrees with the prosecutor's assumptions. Apollo barely manages to convince the jury to have another day to investigate. The next day, Apollo tries to focus on finding as much information about the victim as possible. The victim was an instructor for computer science at Ivy University according to his ID card. Apollo visits the university to find more information about the man, with his tour guide unfortunately being Stickler. Stickler, who for his first year took a computer science course, is able to provide a little information about the man. He had just recently returned to Ivy University after a (very) long vacation. After Apollo does some more research of the man, asking his various colleagues, Apollo finds the man's office. On there he sees a picture of the defendant. Upon asking Stickler, Stickler reminisces about his first day and when he first met the professor. The professor had introduced his wife to the class, the woman in the photo. The wife as suffering a disease, but was hoped to survive. However, one day before the victim's scheduled vacation, his wife died suddenly. The victim mentioned how he was not allowed to see the body to his students and left sullenly to his vacation. Wesley remembers how he felt awful that day, especially since he found the woman to be particularly beautiful. Apollo gets and idea and leaves to visit Ema. He explains to Trucy how he believes that the woman never actually died, and instead just returned to visit her husband. Ema mentions how she had had the theory, but it turns out they had had the woman's DNA on record. The DNA samples from the women did not match. The second day ends with Ema hinting the possibility of a twin. The next day of court begins and Apollo is unsure whether if any of the previous day's investigation would help him at all. Trucy reassures him and they begin the trial. That day in trial the prosecutor mentions how s/he cannot help but find the defendant familiar, Apollo agrees. The defense argues the question how no one really knows who the defendant is. As they obviously cannot summon the defendant they instead they argue about the defendant's similarity to the victim's wife. The prosecution argues how that only supports the prosecution's case. The defense then summon a colleague of the victim's who gives his account of what happenned to the wife, the colleague also vaguely mentions a side project of the victim. The defense then summons the doctor of the victim's wife. The doctor says the the wife was certainly dead, but when he saw how the victim was madly in love with the woman, he would not allow him to see his wife's corpse out of pity. The doctor also makes it clear that the wife never had a twin in the first place, which is something the defense was just about the point out. Unable to find anything to do next, and knowing that if they do not tie the last few testimonies to the case at all that their client would be found guilty, Apollo does not know what to do, until Phoenix stops the trial. Phoenix apparently was in the audience and when he heard something about how the man was working on a side project. At that point he left in order to do some investigating on the victim and offered to testify. The judge accepts Phoenix as the defense's last witness for the day. Phoenix brings information about the victim's "side project." During his vacation, the victim was distraught, however, the entire point of the vacation was to aide the law department in a little "project." The victim could not back out of his job. He was the head programmer of the new "bar exam." (Finally Apollo and Fran 2.0 realise how they recognise the defendant). Both and Apollo and Phoenix explain the rest: He was in charge of the coding and... had an input in the character's design. He was able to have the aide based completely off his dead lover. In a way, the bar exam became an homage to his dead wife. Finally explaining a mystery, the prosecutor brings one problem to the conclusion... that did not prove in any way how the defendant was guilty. Phoenix began to explain, "The defendant... she's the wife. She doesn't exist." The prosecutor began to protest until the Judge interrupts "I think understand what you're saying, Mr. Wright. It brings back memories. I'm glad your apprentice was on this case, only you would be able to figure this out." The Judge then orders the defendant to be brought back to the stand. The Judge seems to be taking the lead in questioning the victim, as soon as she returns to the stand, she seems to be a nervous wreck. The Judge corners the defendant, "You understand where we're going with this don't you?" The defendant seems cornered. "Why didn't you tell anyone... you were dead?" Apollo suddenly starts asking questions and protesting. The defendant seems to stay calm and replied "You wouldn't believe me... and I... couldn't leave yet." The defendant begins to explain furthermore the entire situation between her and the defendant. She then explains what really happenned. The man wanted to see his love one last time before he finally committed suicide to join her in heaven. But... in the end... she couldn't leave before he killed himself. The woman went hysterical before her dead lover. Though she knew she could maybe see him again, she couldn't leave the world with things the way they were. She began to cry over his dead body. (OR SOMETHING, I DON'T KNOW. I'M NOT A WRITER) Finally, the ghost decides to leave, and in kurain spirit chanelling technique, we see a slightly familiar chaneller, who's name is never revealled, but the Judge seems to recognise her. "To channel someone for so long... why did you do it?" he asked. The girl responded, "I sympathised with the man. I understand how it is to only depend on one person for so long and then... have them just taken away from you... and you can never see them again. But after that... that man had nothing. At least I had people to hold on to... two very important people. But he had nothing. I felt sorry for him." The trial ends, we never hear from the chaneller again. The Judge or Phoenix explains the entire thing for only AJ players and fin.

everyone she ever loved ended up leaving her
