Surrender, but turn on your communicator to Tyrell. Whisper into it that you have been captured. Options after this is to either send an EVAC team, or to have The Privateer's Blade follow the fleet. However, since they would likely be taking you deep into the Hedgemony, it is likely that following would be a very bad idea. In this case, we need to see if an EVAC team is plausible. In any case, leave your communicator on.
In sending an EVAC team, we would need to sweep in, and sweep out quickly, get back up to the ship and warp as fast as a mofo. You would also have to back their attention from the hostages.
Boy, this is a tricky situation…
