Okay I forgot Darklaw was even the prosecutor tbh.
What was she trying to prosecute Espella for though? Like was there an actual crime scene with a set of circumstances and evidence and witnesses to go through, or was it like "well you did this crime and to explain why, I am now going to go back 20 years and talk about the past... (where we also will not get into any particularly ace-attorney-like specifics of the events)"?
But there's no point in answering me, I really don't remember the details of the case. I don't even have any clue what the three different components listed in the OP are. All I definitely remember is that while playing it, I felt like it was just the end of a Layton game where they explain all the mysteries and stuff, but they had to have a courtroom and a judge and a "murder" but it wasn't at all the most pressing part of the case.
