He only cowered because his comrade was forced to betray him. Something he didn't think was possible. It possibly scarred him. Not to mention he felt actual pain.

He went back to train because he was defeated very badly. Maybe he feels he needs some alone time with Seiger because of what happened. Also I kind of thought that the training was a regular thing for him.
