After many hours the Epistemus was repaired. They tested the Master interface built into it. Cosmos began the transformation protocol. Deep Dive transformed into an engine that embedded in the Epistemus' robot mode chest. Normandy transformed into a head that became the Epistemus' robot mode head. Spartan was not needed for the Epistemus robot as he was just a weapon to be held. Once the test was successful. They reverted back to normal. 

Once in outer space they launched several missiles at the derelict Decepticon ship. They aimed the ship's weapons depot, the combination of the derelict's weapons and the Epistemus' caused an explosion big enough to obliterate it.

Cosmos then picked a random direction and flew that way, within in moments he began picking up transmissions from something. After running it through several filters he was able to determine it was coming from someplace call DS9. He picked up speed and was there in five minutes.
