Mafia 47. Battle of Movie Heroes

Where is your chain of reasoning? Please provide the copy-paste.

Clue for the first day's murder: "Death and the Maiden" is one of Schubert's works. Schubert's works belong to classical music, which is indicated in Mortulus's profile. Additionally, the motive for the murder can be added: in the last mafia game Mortulus participated in, he was killed by Thorium. This is partially confirmed by the fact that Mortulus almost always targets those who offend him.
Next.
Mortulus's behavior is always approximately the same, but I don't recall him ever showing any grand analytical insights. Therefore, he could have easily ignored the tempting opportunity to frame What? or Jack and continued to kill. But on the second night, Potter visited him. That's why the murder didn't happen.
