After Rolf had successfully found his ammunition, some strange music, not sounding unlike the victory music from Final Fantasy, maybe a motion sensor in this part of the ship that didn't get taken off or something. He shrugged it off, and walked around some more, hoping to maybe find some more useful or curious items. Though largely unsuccessful, Rolf still enjoyed the exploration, he got to study the alien cultures. Curiously, they took anything they wanted, but why they thought a high school medal had the same importance as a WWI ration, nobody will ever know how they survived, and nobody will probably ever know how these aliens think.
Interestingly enough, there were many people of the group of human survivors that were congregated around one specific door, that Rolf happened upon during his wanderings. Rolf, like any normal human, decided to walk toward the door, and find out what was so interesting about it. From conversation that he heard, Rolf learned that one of their own, the musician, the female one, was stuck on the other side of the door, and they were trying to get her out, specifically through explosives. Communication was through an air vent. That got Rolf to thinking. "People, people. Before we try to blow this door up, and possibly cause severe damage to this thing, or anybody here, why doesn't the woman climb through the air vent. There's an opening on both sides, and it looks big enough for her to crawl through, on this side at least."
