Dex was about to answer when the Commander of the mission came and stopped him, cutting in as Dex opened his mouth to speak. Dex listed carefully to the commander and when he sensed that the man was finished he spoke, "Nice to see you with us Commander," he said casually, extending a hand, "It seems that you've read my files, because you know my name before i introduced myself." He did this of course out of curtesy, not wanting to piss this guy off either but he didn't really care for the man's name, he probably wouldn't use it anyway. 

He turned back to Callahan, "When exploring space, darkness is something that people come across easily. Yes, I have killed people," He said, resting his hand on the shotgun he propped on a console and running his hand down almost three dozen notches in the synthetic fittings, "Though most of them deserved it, so I feel no remorse." He picked up the lever action shotgun and handed it to the pilot, notches facing her, "But one never forgets." He turned away from her, feeling he made an elaborate enough statement, Instead he concentrated on the dash and watched as the coolest levels rose and the pneumatic pressure increased.

"Clear for take off." he said, watching as they ejected Ronica's capsule down to the planet.
