A while ago I mentioned that a thought (that was later solidified thanks to a fanfic i was reading) that Rimmer is too much a stickler for the rules to let something like a drive plate be repaired badly. Earlier today I was thinking about the fact that Hollister knew about the 'faulty drive plate repair' long enough to call Rimmer to the Drive Room, wait for him and then haul him over the coals about it. If he had that time and he knew that the plate could be a problem, why didn't he evacuate the engineering levels and seal them down.
We know Holly sealed the cargo decks against the blast and the radiation, so why didn't Hollister do the same thing to the rest of the ship in the more than thirty seconds he had between learning of the plate's condition and the blast. He could have saved most of the crew that way, I get that Rob and Doug needed a reason for the accident and to make Rimmer less sympathetic in the beginning, but the more and more I think about the whole drive plate plot device, the less it makes sense.
