The other thing re Jack - he's a highly sexual person, and saying yes to a golden shower etc, and talks a lot about it, and is very touchy/huggy etc, BUT as Alessandra said, he doesn't even seem to want to kiss Tori, and then offers her up to sleep with another of the grooms.
The difference with Peggy is that she pretty much said sex wasnt close to being a priority for her, and that she reeeeally needs to trust someone before going there.
