One thing I didn't know how to convey visually well enough to ask the artist for it is Wind Whistler's side of this — it's not just how she talks, but comforting someone is hard when your brain works so different from those around you. She's putting EVERYTHING into perfectly replicating what she believes a comforting smile looks like, and she knows she can't promise anything, let alone "everything," will be all right but that's what you say, right? It's this weird acting-but-it's-not-acting that you have to do when translating yourself for people who aren't in the "knows pi to the zillionth digit but always needs the joke explained" club, and she's terrified she'll make Fizzy feel worse by screwing it up.
