There we gooooo! I THINK you were going for them being situated on a ship of some sort, from the end part of your post so I hope its okay that I kind of threw them into one XD 

If not it could always be a red herring designed to lure and capture them or something too Haha 

As far as Revan's reactions, I imagine while he's normally a cool, calm and collected master of strategy, he still has a tendency to have "blinkers" on at times when his close associates and friends are concerned...
So the same stubbornness that meant he refused to give up on Bastila when she fell to the Dark side in KOTOR is sorta working against him here because he feels hes let Meetra down enough times already by taking so long to rescue her etc so hes kind of willing to risk it being a trap if it means he can get her freed if that makes sense? XD 

Could work that into being part of the reason why the mission ultimately ends in Meetra biting the dust, if it works XD
