(Spoiler) Starting from minute 9:00 I'm tackling the clock riddle.
The clock in the apartment shows the wrong time, you notice this when switching between the real world and abe's Imagination. Then you align the pointers with 1h later than before and you get a new time, his actual time of death. You need to tick "what if joshuas clock was accurate" as well as "what if joshua committed suicide" and then solve the riddle in the imaginary world 😊 talk to ben afterwards.
