It takes Ted a bit to change - the cast does not make things easy. And while he's not quite as sore, his ribs aren't fully healed either, so changing shirts and such does take a little bit of work. He returns after a bit though, now in sweatpants and a soft sweater on top of his barbecue t-shirt, and with freshly brushed teeth.

He also makes sure to take some painkillers while he's not in the room with Sherlock. (He doesn't know the specifics of his addiction, but he knows it wasn't alcohol, so that narrows it down a little.)

Ted does a slight double-take when he sees Sherlock in a t-shirt though. Mostly because he wasn't expecting the tattoos. He doesn't comment on them though, instead just goes to sit down.
