Encounters on the Serena Dawn

Seedy disreputable type is seen interviewing for the expedition same time as the PCs but is rejected. He then turns up as new hire on Serena Dawn crew as a deck hand. He and one or two others are pirate moles who are working on the inside to help with capture of SD. One plot is to plant a bomb on the weapons locker on the bridge level. Another plot is to reprogram a robot to help subdue the PCs and ship's crew. Another plot might be to poison the capture to cripple leadership on ship. And a backup plot would be to dawn a vacuum suit and bomb or cut loose the cargo module that contains expedition equipment (including more weapons).
