Strange is looking between the veggie and cheese pizzas, deciding which of those two he's going to pick out, when Rita asks her question. He whispers back, so as not to embarrass Rita too much,

"It's an island in the Pacific. I've no idea what it has to do with pizza, as I haven't been there myself—"

But then he cuts himself off. Because there's pineapple on that Hawaiian pizza. He went literal months without having to possibly deal with pineapple and now he's encountered it twice in a few weeks? Strange's expression shifts to a frown, as he shudders slightly and gives the pineapple pizza a look.

"Don't get Hawaiian, it looks disgusting."
