His earlier hunch to mention Palpatine, to expand on what the current political climate is, has become a growing suspicion that is merely confirmed when Jacen explains that for him, Palpatine was killed five years prior to his birth.

Reclining on his chair, Obi-Wan crosses an arm over his stomach, supporting the opposite elbow while that hand reaches up to tug absently at his beard. For anyone familiar with him, it's his classic calculating pose, considering all the possibilities and outcomes of any given actions. How had this happened? That it had happened was clear - Jacen is proof that... well, somewhere, there is, or had been, a temporal anomaly. It had always merely been conjecture, as far as Obi-Wan is aware; a mind experiment, batted around by the philosophy and physics students and scholars.

And yet.

Well. Nothing for it now. It is always best, when one is unsure how a situation will ultimately play out, to move forward one step at a time, staying attuned with the Force and waiting for guidance. To that end, Obi-Wan drops both hands to hit his knees with finality, before pushing up out of the chair. "I'll go look for your lightsaber."

He pushes the still mostly-full glass of water toward Jacen. "Drink. Slowly, but finish it. You may not feel it yet, and your healing trance surely helped, but I guarantee you're still dehydrated. I have plenty more, don't worry about quantity."
