Wash had thought they were done, honestly. That Tucker would nod and following him back to the others, maybe chewing on the conversation a little to himself. But instead he keeps on the topic, and Wash isn't sure if it's an incredible insight into his headspace or something else. For a moment he's worried it's the former, and that Tucker will keep pushing until he knows the truth, which he won't like. Luckily, he keeps speaking. Something tight and annoyingly hopeful flutters in Wash's chest at the next statement, but then an admission. And his focus shifts back to Tucker's well being entirely.

"I do now. But I hope this was the last time you ever have to." Something about the way Tucker says he'll do whatever he has to makes Wash worry. About if there ever comes a time it's not worth it to chase after him.

As for the admission, he hesitates. The fact is, it's war. Everyone does shit they're not proud of. Sometimes it's necessary, and sometimes it's not... Wash himself has done a lot of both. Has to live with the guilt over the things that weren't, the things that were all just him making bad choices, doing bad things. But 'shit I'm not proud of' is slightly different from just making the wrong call. He needs to know if they're tied together.

"Do you just mean the mistakes? Or something else?" And does he want to talk about it?
