Regulus makes no attempt to memorize the code, both due to unfamiliarity with electronic locks and that he plans to never come here again once this is over. He'll quickly set to work, with occasional glances back towards the door they arrived through. Though, he does have to ask, "What was that dragonish thing back there?"

Mikoto is also fast to do as told in this instance, after all, it's what they're here for. Some smaller items she even grabs with her tail, just to speed things up.
