I don't know if Delilah is the blackmailer. Could be, might not be. You're accepting Delilah's words as truth, when Delilah in the moment is projecting a very shifty disposition that 99% of adult humans would notice. Just because you can't, doesn't make you correct. Just go back in this forum and count how many different users point out how suspicious Delilah is in the bus scene, and how unlikely her story is to be true after the earlier scenes. There's a lot of people that saw something up. Ignoring that is on you. Saying that view has no arguments is just ignoring reality. You can say you're not convinced, but saying there is no case to be made, because the suspected blackmailer said they were innocent is really, really, really, dumb.
