Kel
It isn't the new arrival's tattered clothing that goads Kel into action; it's the way the newcomer immediately went for his weapon and squared off against Rhys, without so much as a word of inquiry or warning, that tells the former CorSec officer all he needs to know. He extends his weapon past the corner and carefully lines up a shot at the newcomer. "Hostile! Hostile! Engaging target!" he shouts.

Attack: (1d20+5)[10]
Damage: (3d6+1)[17]
I'm assuming that the target is within 20 squares and that Point-Blank Shot is therefore in play; I'm also using the corner to provide cover against the dark Jedi.
((EDIT: Figures. A lousy attack roll, so of course this'd be the time I roll near-max damage.
