Clara made no sense...
Two huge things I didn't get it that seem to have could've avoided all their troubles:
1- Why didn't Clara destroy, bury or hide the bodies of people she killed? The guy she decapitated obviously wouldn't have burned entirely and someone passing by would report a fire. Guy on the beach and teacher on the piano... um they're going to get discovered and youll be tracked if you just leave them out in the open. How did she not have enough common sense to just cover her tracks?
2- Why not just tell Eleanor that they'll be literally killed if she goes around telling people the truth about them being vampires? She knew she was being pursued by dangerous men. Why not just tell Clara so she'd understand the situation and wouldn't going around making things more unsafe for them?
Maybe i missed something, but it seemed like simple issues were overlooked completely.
