So, here are my thoughts:
Mold is a mobster, he killed Hermit.
Captain framed Lizard (Yesterday, Lizard was caught red-handed defending Striped, while the evidence against her was obvious. Also, Lizard was checked the day before, maybe a spy was checking him, hence Captain's decisive actions).
Revan was Falco, defending Arandor and got caught in the crossfire of the demonologist.
but not so much with the third... maybe Revan was a priest or a spy and ran into the demonologist?
