He's not. And it shows in his posture, subtly, if Havelock can read Trowa's body language in his own body. This is not relaxed affection, but the waiting poise of a deliberate choice to trust, for this moment, and not pull away, for this moment.

But Trowa's still standing next to the ballerina on the magical vines, all the same.

He meets Havelock's eyes (or his own) calmly. The silent greeting says something along the lines of well, it's worth a try.
