How do I confirm Henry's escape route?

[19thperson]

Last thing on the list. I've exausted everyone's conversations and relationship levels. Not sure what to investigate. Will it just manually fill in if I try to walk from the prison to the crime scene?

I think this will be cleared if you check where Henry started, and where his end point was, that being the blank space in front of Henry and then check the end point... which if I'm remembering right, i think it was the 4th seal, the spinning eyes?

[Devilfish]

If I remember correctly the start point is the Desolation cell, the end point is the Council entrance and there's a Nightmare Computer in between those two points that also has info on his movements.

Henry also mentions something in conversation during one of the later "hang out" conversations. That he saw New Night at some point during his escape
