Right... I don't really care where Hissra walks. I'm sure he'll stay close to Shok, at least to start. He might eventually move about to stand and talk with whatever new friends he makes.
In the camp he will likely keep to himself to start, just watching from a distance. But he will slowly become more social. He will be drawn to the other mages immediately, out of curiosity to how they are raised and taught. He will want to learn from them.
I can't see him sleeping in a tent really... But he might be drawn to the enclosed space of one anyway, after having spent most of his life in confinement.
