"Spoiler warning for Dual Destinies (mostly the last 2 cases). Blackquill, a prosecutor, was trying to figure out the identity of The Phantom, an international spy. So The Phantom killed Blackquill's biggest ally, which forced him to take the blame for the murder (to protect this person's daughter). So he ended up in jail for a crime he didn't commit. Six years later, The Phantom assumes identity of detective Bobby Fulbright, and under that disguise works together with Blackquill, who was allowed to prosecute again (despite being on death row). Their dynamic somehow contains a two-way power imbalance, since Simon is able to boss "Fulbright" around and insult him (being his direct superior), yet also "Fulbright" is technically his handler, and solves Blackquill's behavioral problems by... tasing him. They work together for most of the game. The Phantom forced Blackquill to take the blame for yet another murder. After it was revealed that Bobby Fulbright was in fact The Phantom in disguise (a man he was chasing all these years, the one who ruined his life, ended up right by his side), Blackquill cut his mask, thereby causing Phantom's breakdown. Blackquill took The Phantom into police custody at the end of the game. The jailer becomes the jailed. Great stuff."
