Maybe it's just me, but all these scenes with them together: they're on the cusp of innuendo. His beastly side seemed way more aggressive but I don't think he was strangling her to kill her but more to possess her, take her. That's why I think he went to go sit in the lake, to cool off. He is very, very careful not to overstep the boundaries he's placed between him and her, otherwise.
Do y'all think that Elias was really trying to eat her and the dream about her mom was really Elias strangling (or beginning to) in her sleep?
