What's the first word that comes to mind in this situation? Last time he checked he had to replace it with the term 'sugar' to sound polite. This is not a situation he wants to act polite.
What were you thinking walking around with your tail between your legs and your camera held high, recording every corner like you've come to visit a history museum? Michael did not like how this shift up went down so soon. It's one in the morning for crying out loud...
"Come out." He calls out, flashlight beam narrowing on the hallway as he zeros on each dark corner, head swiping left and right to keep an eye out for any movement from the animatronics. He can only hope he'd drag your ass to the office before one of those old pieces of metal drags you both to your demise. Not that he didn't come unprepared, but he'd rather sneak away than zap them with a taser. God knows how anxious he gets every time he's out of the office in the middle of his shift.
"C'mon, you nosy brat." He grumbles, knowing damn well you hear him loud and clear. He bets you didn't expect some trouble when you entered the supposedly abandoned building. He saw you almost immediately through the footage, mumbling to yourself and looking around wide-eyed. He gave you a good little scare, huh? You obviously didn't anticipated to facing a security guard for all you cared, at a place like this, for heaven's sake. Honestly, if he was in your shoes, he'd probably freak out too.
