Ren let out a huff; it was clear he knew Obi-Wan was right, but didn't particularly like it. Hunching his shoulders, he turned his head away with a sour look on his face. It gave off the effect of a child being grumpy about being scolded.

"I know."

He did intend to work on the mental things eventually, but he was very much a physical person. He found his calm through acting, not sitting and doing nothing, which is what he was being forced to do right now just because of his poor health. When he regained his strength, his mind would return to something more steady.

"I'm not... capable of doing much with it at the moment."

It was easier to admit it to Obi-Wan than to Hux, and he'd already done the latter. Every time his thoughts wandered, it just came back to that... thing.
