"...I gotta agree with Snake. It's not like we're promisin' to go steady or anything." Heiji agreeing with Snake on a major game decision, how weird...

"More information at this point is better than none, and it's true we don't know how to get the power back on. And if a generator or something like that is actually damaged instead of just needing to be reset, we won't have the tools or knowledge to fix it. Unless one of us is an electrical engineer, which I'm kinda doubting at this point. So I'm willing to give it a try."

Besides, they could always gleefully betray Zero later if they got the opportunity. Normally Heiji didn't approve of such shenanigans, but the guy was kind of a grade A douchebag/kidnapper/accessory to murder, so.
