The most cursed in my mind is obviously Lana/Leanne dating Phoenix, but if we're going on something that would be most devastating to the plot, it's probably the fact that Neil Marshall is alive. His death was crucial to solving the case and proving Lana innocent. Did they replace Neil with another murder victim, or does that part of SL-9 just not exist?

They replaced Neil with another victim. There’s a character named “Rong” who was Joe Darke’s defense attorney, making SL-9 a thing

Ah, okay. Also, if Ema doesn't exist, who was the leverage that Gant used? I assume they replaced Ema with Maya, but if Ema isn't there, who was there to witness the murder, and then cause Lana to be subjected to the blackmail? If they made Maya the witness to that murder, I swear, I'm going to scream. Why is this musical so unnecessary?

Neil basically replaced Ema with the witnessing, and Maya was an assistant. I don’t really know too much after that.

Hmmm, okay. Thank you for answering! Now, my question is, why would Lana want to protect Neil? If the plot for blackmail is the same, then this just makes no sense, honestly. You don't need to answer this though, I just have so many questions for this disaster lmao.

I don’t know. I never really payed attention to SL-9 in the game, because at the time I was just using a walkthrough and was excited to play Justice For All. So I basically skipped the last trial and just presented things.
