I find it interesting that Leticia, Carolyn or whoever is able to intimidate Gerard into stopping what he's doing. He's not happy about it (or anything else) but he does do what she says.
If Maggie is supposed to be in such grave danger, why don't they put her in restraints?
I'm not buying the excuse that Julia gives Carolyn about mailing instructions about the care of the children to Windcliff. Yeah, it's 1970 but wouldn't it make more sense to use the phone? Especially with mail taking a couple of days to arrive.
