I'm not the authority on any of this, but from the come people we've seen who left and came back again, they went right back to the moment they were taken from. They didn't remember being here, or anything that happened until they arrived back again and suddenly it was all jammed back inside their head.

I'm not sure how equipped I am to take on Loki-level enemies, but if anyone comes here looking to hurt people I'll do my best to stop them.
