Tabor Calchek, the crew's (apparent) employer tells them they'll be in big trouble if they don't do another job for him at half their normal rate. He hires them to salvage a freight ship that had some sort of catastrophic meltdown, leaving no survivors.
The Android tells Five that the computer chip she found in the room with the dead body is not data storage, but "part of some larger system designed to access pockets of extra-dimensional space." Neat!
Two discovers that a contagious virus broke out on the ship, turning its crew into monsters. The virus was not airborne but rather transmitted by fluids like blood and saliva. Her neck wound could be a major problem.
