Far as the Kevin/Aimee thing, yeah, there's something inappropriate and/or creepy there and like you. I wonder how far or even if they delve into it. I thought they were going in that direction when Kevin and Aimee were at the house alone and she said matter of factly, "You don't remember what happened last night do you?" or something to that effect. I also got the impression by Kevin's "We like having you here." response and basically ending that discussion be going upstairs that he wasn't so keen on hearing what she was gonna say either.
