As it happens, Rayne, that 'trial and error' got the Barge back in working order when we crash-landed on the Master's planet and when most of the systems later failed for no reason. 'What little we've managed to figure out' has saved the lives of everyone on board. The engine has needed care and maintenance since it was exposed in the crash and we've been providing that.

Yes, the Wardens maintaining the engine room are self-appointed - as is every Warden with a job on this ship, I'd like to point out - because we're the most qualified for the job. If it's a thankless task, then it's because of people like you underestimating and undervaluing the contribution we make to keeping everyone safe.
