"Oh, no need to buy one," Ted answers immediately. He's assuming the danger is in him going home, because he'll be easy to trace, and not because there might be a bomb planted there or something like that, so someone else should be safe.

At the reminder of Henry though, Ted looks disappointed. Talking to him is such a matter of fact, it didn't even occur to him that he can't. "Oh... Yeah.."

He picks up the phone and texts Henry, letting him know that he can't talk tonight, but that he loves him very much and they'll talk soon. He definitely looks sad when he puts the phone down again.
