"I don't know," Keith snapped, angry. "Maybe there is." He'd dealt with people all his life wondering if something was wrong with him. Tony had hit a nerve. He pushed off the wall, floating backward into the water, almost like he was going to end the conversation like that.

But then he sighed, deep breath in his nose and then slowly out through his mouth. He'd been trying to work on that temper... see? It didn't fade completely, though. There was a still a sharp edge to his words as he continued, especially that last part.

"Honestly, it's as close as we have to a base of operations," Keith said. "It was something that helped when we were in space too long back home. Having a place to come back to, real air, real gravity, a real solar cycle... Not everyone can spend unending time in space, even on ships that simulate a planet." Keith had done that... They had a pretty decent set up on the Castleship, but touching down once in a while helped a lot. It had been even worse when they'd lost the Castleship and were down to just the Lions. "And while we didn't have a base planet to go back to, touching down on the different planets through the trip... it helped.

"Plus... we had to make sure our ideas worked on making sure things were working here. And, well, we promised we'd come back. We headed out to that place because we needed to, and we came back because we said we would. For some people, giving your word means something."
