[Rocket goes silent, having hit the point where he no longer has anything to say in agreement. As brutal and awful as his life is, he's never thought about ending it permanently. If he did, the whole hero thing would have appealed to him a lot more- at least make an inevitable demise mean something. At least he'd understand why Groot and Yondu chose it.

But that doesn't mean he stays silent for long. What would normally make him just shrug and think "not my problem" has him suddenly pressing forward.]

Whoa, whoa, whoa. Dude, you can't think like that. That means the other guys win, and that's about the only frickin' thing that guys like us have.
