Flat-out refusing to unpack a conversation? Couldn't be Heero Yuy

"Flight suits."

Heero's expression remains still as stone, but there's a subtle impatience in his tone that suggests he suspects Red might be simple. The idea that a spacefaring man can't even fathom a ship without bathrooms or a full crew is somehow more distressing than the fact that the pilot he's speaking to seems to be a dog-person.

(Of course he has an anus? For the stick.)
