Pope's rant about the proper way to cook chicken in "Prisoner of War" comes completely out of nowhere. The man does not tolerate bad food..
Later, in "Sanctuary":
Pope: I smell asparagus. That means you're boiling it. That means you're ruining it.
"Dai is high as a freaking kite, but loves this bread."
"Dai refers to himself in the third person now?"
"Sanctuary Pt. 2": While the 7th Mass have Hal and the kids pinned down, we get a quick cut to Clayton calmly telling one of his guys how he once considered buying in this neighborhood.
Pope's beloved Harley motorcycle getting destroyed by the Skitters. He does not take it well.
Right before the big damn battle against the Overlord, Click, Dai and Margaret snark over how stylin' Weaver's battered jacket is. Weaver's reaction is priceless ("Alright, stop it, or this stylin', rugged, side-eleven boot will commence to kicking some ass!")
