Amoral Attorney: Prosecutor!Phoenix jails his girlfriend's sister and cousin without allowing the defense the oppurtunity to find the whole truth. Franziska von Karma is like her canon self but without the Character Development. Possibly Lilie Heatherd
Batter Up: Maya conjures a baseball bat up, seemingly out of hammerspace when she tries to chase Phoenix out of Edgeworth's office.
Big Eater: Not only is Maya as junkfood obsessed as ever (The fic actually makes use of both her US-Version hamburger addiction and her JP-version ramen addiction) - she even tries to actually use this as an alibi in her testimony - there's also Lilie Heatherd, who's basically a walking food-lexicon.
Bilingual Bonus: Translating the German in Chapter 22 leads to rather... disturbing revelations. Franziska has a wound in her (right) shoulder from being shot by her father. Also, Gregory Edgeworth was the victim in the BD-7 case, and Dahlia is heavily implied by von Karma to have something to do with it.
Bizarro Universe: A minor and actually well thought out example; Edgeworth fufilled his childhood dream of being a defense attorney. There is no reason yet given for Prosecutor!Phoenix's career change.
Brain Bleach: Directly referenced at one point, when Phoenix comes up with a particularly disturbing image*
Phoenix: (Yikes! Somebody, pass the Brain Bleach, please!)
Couldn't Find a Pen: Very nearly defied by Phoenix, who notes that every single time this trope has happened in his universe, the note turned out to be from the real killer instead of the victim. He nearly tells Gumshoe to destroy a note supposedly written by Ema Skye before Edgeworth admonishes him, stating that even if the note is obviously fake, it could still help them find who really wrote it.
Counting Sheep: Phoenix tries this to get some well deserved rest. It works.
That depends on your idea of rest. *shivers* the nightmare...
Mia states that that isn't actually Pearl, but something copying Pearl's shape from Nick's memories. Note that this isn't actually helping anyone, because we don't know who this spirit actually is and why s/he has it in for Nick.
The moment this whole implication turned out to be true, I would just do like the first PC I ever handled and suddenly shut down, accompanied by a weird, blue screen telling everyone that I 'encountered a problem'.
Manfred von Karma being the one found guilty of Gregory Edgeworth's murder.
Kay Faraday still becomes the Yatagarasu, but she's working with Raymond Shieldsnote The fan localized name of Tateyuki Shigaraki instead.
Zak Enigmar's trial ending with him disappearing.
Jerk Ass: Lilie Heatherd. So far, she's been an annoying witness, obstructed a police investigation because she didn't want to be bothered, disrespected the court where she works, been a bitch to Maggey, and being all-around immature.
It's later implied that the possible reason she got together with Dylan Sengage is that she could pin the murder on him...until it's revealed he's genuinely her Morality Pet and the last person she wanted to be branded as a suspect.
Jigsaw Puzzle Plot: Because asking outright would not be one of Phoenix's brightest ideas right now. The reader is very much welcome to look over the court record and speculate.
Meido: Maggey, once again. But this time the dress is pink.
Mirror Universe: Avoided. Despite at first looking like one of these, the differences between the two are a bit more complex then a simple morality/position flip.
Mood Dissonance: Find out more about this world, maybe it's not so bad: No DL-6, Mia and Misty Fey and Gregory Edgeworth are all alive and well, happier childhoods for both Edgeworth and Dahlia, Maya is living the dream as an idol singer... and then they enter the apartment.
Mythology Gag: During Maya's song, her voice quakes when she sings the line "And my miracle will never have happened" so that the last word almost gets cut short.
Phoenix Wright at one point alludes to the Mob Trials from the Layton crossover.
Older than They Look: Lilie Heatherd. She looks 15. Her actual age is 23. Her personality doesn't help much and neither does the fact that she tends to exploit her youthful looks to her advantage.
The Only One Allowed to Defeat You: After the IS-7 incident trial, Gregory Edgeworth always took up cases where von Karma was prosecuting, having taken what happened to his client and his client's ward personally.
"Pearl" is a spirit, most likely malevolent, who's taken Pearl's form through Nick's memories. It's not the actual one, but we didn't know that at the time. This leaves the question: who is that girl?
The Reveal: Chapter 29 reveals more on the fate of Gregory Edgeworth since December 2001. As it turns out, he had been taking cases against Manfred, and this apparently leads to his murder, the BD-7 Incident. Dahlia was the defendant in that incident, and in the end von Karma was the one found guilty. Prosecutor!Phoenix was the one who was supposed to prosecute the trail as well.
Running Gag: A lot of things Phoenix encounters on the second day just happen to be pink. Among them: The Hello-Kitty themed cafeteria deco, Maggey Byrde's new uniform, Maya's mysterious letter, the blossoms of the cherry tree down the river and Kay Faraday's shirt. It would have more if Sōta Sarushiro's pink hoodie were there to.
Subverted in Gregory Edgeworth's case as of Chapter 29; he was still murdered, but in a different case (the BD-7 Incident). Not even in an Alternate Universe can he be spared, apparently.
Squee: An absolutely hilarious example occurs when Edgeworth notices Phoenix has limited edition Steel Samurai trading cards. The fact that you can see the canon Edgeworth doing this makes it even more LOL-worthy
