Ted is definitely also scared, and he's not quite as good at hiding it as Joan is, though he's trying for her sake. He gives her hand a little reassuring squeeze, that's for his own benefit as well. At least he gets to sleep right here next to her.

He's also definitely not going to be able to fall asleep until she has, and then has been asleep for at least as long as it took her to get a seizure earlier. There's no way he can properly relax.

He glances over at Sherlock and his laser-focus. He wouldn't want to be watched like that, but it's a comfort nonetheless, even if it's also slightly unnerving.
