What was Longlegs doing to her (spoilers)
During the supernatural reveal that the mother narrates for us, we see a flashback where a young Agent Harker sees Longlegs tying up the mother. What's happening in that scene? ... is rape a possibility? She looks hogtied
I could be wrong, but I think we see a shadowy figure in the background? So I guess Longlegs could be doing some Satanic stuff
