OK, so they've solved the air problem, the power problem and next week and possibly the week after will solve the water problem, obviously Destiny is recycling they're waste so that's that problem solved, that leaves food, which while pressing seems less of an issue since the rations are holding up.
*possible spoiler*
Hmm, I smell someone dying from falling into a lake of liquid nitrogen when Destiny drops out of FTL in range of a ice moon, one of the disposable idiots will step on a weak spot and fall in, being flash frozen in the process.
Also, this "signs of battle" bull****, that bloody ship is 5000 centuries old, it's going to have a bit of wear and tear. Aside from the hand weapons that the humans brought with them, I've seen nothing that remotely resembles a weapon, even an Ancient one.
