[He's completely unaware of the fact that since he left the door wide open so Tadashi and Baymax can see him (and Hiccup can hear him), that door can easily shut. Here's hoping nobody's arm is actually there because he hears it shut completely and he whips his head around.]

Hey! [He turns, looking at the shut door before lifting a fist and pounding on it to try and get it back open. Okay...okay! This really could have gone better and now he's locked out from anything even remotely useful and without his team. Great. He bangs on the door one more time and works on prying it open before deciding that he should probably be a little more aware of the fact that the robot just spoke. So he turns to face the receptionist, blinking slowly and giving the robot an appraising sort of look. (What if he takes it apart? There's always that. But that's a little drastic.) His hand hovers over his utility belt where his gunblade is stored and deactivated but he's checking his surroundings. Even if the receptionist had a computer maybe he can break in somehow.]

...I need access to the elevator. The top-most floor. For research, you know? I'm looking for some information so unless you can direct me to another part of the facility with a directory and some answers...[Because maybe just asking will work. Totally. And if not he'll figure out something.]
