Luc's expression went deadpan as he still found himself looking at the door instead of the girl that he was, at this point, pretty sure was on the other side - because, like.. seriously? Although he couldn't be certain and there was still that niggling fear that maybe it wasn't. Though, y'know, why someone would think he was an axe murderer - of all the questions.. well, weirder things had happened to him, he guessed. And he was also abnormally tall and he guessed that could have something to do with it.
"Not unless you expect me to bludgeon you to death with these Cheetos," he said, and he hoped the comment would disarm her somewhat - though, now that he thought about it, he probably could cause some damage with the sodas. If he'd wanted to (which he didn't, of course), but it made him glad he opted to say Cheetos instead. She seemed like the kind of person who would get more nervous if a real threat (albeit a joking one) were posed.
He had to assume at this point that he was talking to Lucy though. Because, truthfully, if he didn't - well, he would just feel completely batshit insane there talking to a closed door. So he had to make himself feel at least a little bit less crazy. Damnit, and he wanted to smoke. At least he knew the weed was gonna be worth it.
"I, uh - if it's a bad time, I guess I could come back later," he said in that slightly 'too loud' voice to be heard through the door. "But I said I'd bring.." He cleared his throat again, his failed attempt at being subtle - as he was standing in the hallway of a complex he hadn't even been in for a month yet. And he was sure not all of his neighbors were down with the weed - well, at least he couldn't count on it. "Gifts.. annnd.. I did.. sooo.. I dunno?" What he did know that he wasn't going to stand out here much longer - not with the contraband on him and sinking feeling of crazy he had going on. Plus, he was tired of holding all this stuff, really.
