The loud, sudden noise came as a surprise, and Lex found himself jumping at the ferocity of it. It echoed upward, bouncing off walls around them, until it faded away entirely. His free hand trailed behind him on the banister as they moved, lightly enough that it would under no circumstances save him if he were to fall backwards. His other hand absently squeezed Blue's, running his thumb over the backs of her fingers as she warned him about every single step. He matched her laugh, and before he'd realized it, they were already standing on the much flatter surface of the second floor platform.<br/><br/>Instead of letting her open the door, though, Lex moved his free hand from the banister to search for Blue. He found her, or her arm at any rate, and he walked her backwards until they hit something solid. The wall, mostly likely, but for all the attention Lex paid, it could've been anything from a door to another person. His hands moved upwards along her arms, over her shoulders, up her neck, finally coming to a rest at her jaw. A thumb traced over her bottom lip, mostly so he knew where it was, before he swooped in to steal a kiss. "I'm sorry," he lied, evident from his smile. He wasn't sorry at all. In fact, he'd have done it a thousand more times if they weren't on a mission to get chairs. "I just had to do that again." It would've been more correct to say that he had to do it again before they both sobered up, when he would slink back into his antisocial tendencies and she went back to being mad at him for some reason or another.
