seeing as that bruce can physically lift a tractor wheel and cinder blocks with nothing but the power of his super sick abs and waist, he might drag that thing out and get other people to help him with opening it. whatever's in there must be valuable enough he'd imagine

since he found some weapons, could he explore around for more, possibly get a mini weapons cache and ammo going for the others? he's not really ok with people being unarmed especially since you know. killer queens and space suits.
