Ted watches her go, feeling deeply sad about everything. He knows they'll work through it, but it doesn't make it any less difficult.

He sighs to himself, then goes down to the office to grab his stuff and walk home - the one in Richmond, in this case. He knows Joan will likely be over in B anyway, but he wants to be close to the pub, the comfort of familiar surroundings, and maybe a dinner with Beard, if he's not distracted by Jane. (Apparently them 'going as friends' to that event had mended their relationship for the time being.)

Even if today there's a chance of him getting some rough comments from people in the pub, given the loss. But he's used to that much.
