ROOMIE. Hector's sort of not sure what to do with having a roommate SO much younger than him, he probably drew a line down the room when Pendleton moved in and was like "don't cross this or touch anything on my side and we'll be fine." He's pretty anal retentive about neatness and cleanliness, and quiet. And getting sleep when he wants it. And in general, he's just...very professional about the whole roommate thing.
Other characters: Grace definitely is around to scrape Ireland off the floor and will look the hell after him, because that's what she does for her crew anyway. :] Hector finds his niceness irritating so you get that line here, lmao. And Hector is a killjoy with Liam, though I don't see them necessarily getting along. Professionally, yes, though!
