I have not seen part 2 of this yet (I'm on Hulu's schedule), so no spoilers from those who have seen it, please. 
I'm guessing that whatever fried that alliance soldier is related to why the ship is not moving. I'm gonna say that the incoming wormhole caused Destiny to stop someplace dangerous, and now it can't get going again, perhaps because it's using all of its power to protect the inhabitants from the dangerous thing outside. The power surge caused a momentary loss of protection under the damaged bulkhead, which fried the alliance soldier.
Again, please do not confirm or deny this if you've seen part 2.
I'm stating my theory based on facts from part 1 and I don't want part 2 spoiled by somebody saying whether I'm right or not.
