Ted watches them go, and once the door locks behind them, he takes a deep breath. It is actually a little bit nerve-wracking, sitting here. Even if he's not the one about to be chained to the table and interviewed. He finds it impressive that both Joan and Sherlock do this all the time. Though usually not with people who terrorized them. (Though, from what he's heard, maybe a few times.)

He sits there, looking around the room as he waits, as if he'll find something to entertain himself. Obviously there's not much. He's sitting back, hands folded in his lap, his fingers laced together. His cast is visible - he may have intentionally refrained from covering it with his sweatpants, so that Henry's doodlings on them would be visible.
