I'd like to know the answer to this, as well. Seems to have happened a couple months ago. Seems to happen only on DK.

I used Gault for most of the assault, but brought Mako in for the Final cause I figured she would have something to say about it. I expected to let her pull the trigger, or somethong. Just wasting a bullet on him gives blood more respect that Mako thinks he deserves. I left him in his cell and walked away. She liked that. We had better men to face in the Republic scum defending the ship. To shoot Blood would even dishonor those brave souls.
