Reiner smiles, smug at first, pleased by the fact that his best friend still stands tallest. That's as it should be! And it's not as though Bertolt is done growing, either. Who knows how tall Bertolt will be by the time he's nineteen?

(Reiner doesn't think of any ages past that. Twenty will be a sobering milestone, to put it mildly.)

Then Jean mentions Eren, and the nature of Reiner's smile changes. He huffs out a laugh. "Yeah. He must hate that."

(Whoops, did that sound fond?)
