Was your character's initials S H?
I had a game like that today where I was a traitor but also the captain. Early on some random idiot assistant figured he would play a prank on me by knocking me over and taking my backpack - usually rewarded with imprisonment in the brig, but it was filled with illegal syndicate contraband which caused the crew to swoop down on me like vultures. During my burial (some guys dragging me off to the morgue to be cremated) the other traitor barged in, guns ablaze and took out the two scientists who were working on my body and with my access card (captain's, so access to everything) he dragged me to the genetics lab to revive me. It didn't really work out that way, with the AI realizing something was up and sending most of the crew to medbay where the other traitor made a last stand and a diversion which allowed me to get an entirely new identity - I have friends in genetics so I even got some partisan aid covering up for me.
But there I was, without my stuff or even an identity card and with the crew dragging my ally off to the slaughterhouse, yet as they believed me dead I had plenty of opportunity to start over. I did't really know what to do, but I knew the engine wasn't started and I saw an engineer walking the corridors alone... so I figured "I'll say that I can help him get it going and murder him brutally while in there and then steal his access card and engineer stuff!" So that's what I did, when we got in there I started releasing CO2 from one of the cannisters and waited for the gas to spread enough that the engineer would go unconscious - he had no gasmask or O2 supply. CO2 is a silent killer, not showing any symptoms at all before you are out. Part of my mission was to destroy all the plasma on the station, so I then released all the plasma (usually used to superheat the engine) and tossed a welder I got from the engineer in, creating an inferno that burned through the hull of the ship.
With the engineer's stuff I later dug a hole into the Chemical lab storage from the chapel area and started another plasma fire there, and from there I dug a hole through the walls and windows (past a mad monkey who still near killed me) to the escape shuttle. I managed to escape alone which is pretty tricky, as I and some mad bombers together had taken out most of the crew on the station. The only people left alive were either holed up in the bridge or new arrivals that couldn't get past the gaping holes in the entrance hall.
Oh, and some Admin thought this approach amusing (I guess) and renamed my character "the Pink Panther" and started playing the theme song from the old movies whenever I did something, like when I put the engine on fire or started mouthing off against other crew members that they were traitors.
