There was no attack; there was not even a lurking observer.  Kirk was simply filling his coworker in, letting him know a bit more about the encounter earlier.  When Cain said he was busy, but didn’t leave, the guard gave him a speculative look.  “Here, ye be a good fighter.  How ’bout you an’ I have a go, aye?”  His pride stung after being so thoroughly bested earlier, and he wanted to get a better idea of what the visitor was capable of.

Amuné gave the guard an unreadable look.  She was picking up on the uncertainty and tension that came from the men around her, and she wasn’t sure she liked the feeling, nor what it might mean.  It wasn’t entirely friendly, but Cain wasn’t really a threat.  Even though he’d rattled Kirk, and shown the man up, that was a misunderstanding.  She didn’t want her friends fighting.  It was always awkward, being friends with two people that didn’t get along, especially if they had to be around each other a lot, and she wasn’t sure what she could say to make it better.  In the end she said nothing, just turning to see how Cain would respond.

(([@TheMinorFall] And I don't think we need to detail much of the fight either, since I'm pretty sure Cain is /much/ better than Kirk -- the guard won't go down easy, and he'll have suggested no weapons.  Just gotta see Cain going overboard and causing deliberate harm that would not be expected in a spar, and Amune will jump in.))
