When Sherlock rises and sits down on the other side of Joan, Ted gives him a smile and an approving nod. There's not much they can do, but if Sherlock's going to sit and be worried anyway, it's better that he does it in a way where he can comfort simply with his presence.

Ted wonders about what they'll do - he assumes Joan will want to be there for the funeral, and Ted definitely wants to be there for her. It probably won't be a very long visit for him, but it's two weeks till their next match, so he's got some leeway. For now though, he just sits there, stroking her hair and gently rubbing her back, just soft soothing gestures.
