It seems to me that Roy speaks more informally to Julia ("I was just surprised you wanted to.") than he does to Vaarsuvius ("I wouldn't know to whom to turn you over."), or, at least, he is more willing to end sentences with prepositions when the person with whom he's talking is Julia.
He ends a sentence in a proposition in the second panel with V. Which makes sense Roy doesn't seem to be the sort who cares about non-existent grammar rules.
