(potential minor spoilers ahead about the final weeks/ negotiations)
I've heard talk of blackmailing different people, but how can that be done? I've found out a few secrets about people (e.g. Blain's), but I never seem to get the option to blackmail someone? When should that option present itself? I was thinking maybe you'd have a conversation with them during week 7 where you get that option, but this hasn't been the case - what am I missing?
