It is so tempting to get the last word in, to instigate again as 76's back is turned. A cheap shot would definitely rile him up, for sure. But he knows it won't stop there, and it'll only escalate into full-on violence. Again. It would also be less likely to summon backup or something to subdue them here on weird camping trip planet. The possibilities.

But nah, save that for another day. A more thought-out and planned day. He lets 76 leave with the last word, just stewing silently in his utter annoyance for the situation he's found himself.

Oh, he can kill you, Jack. He'll find a way.
