Given the circumstances Crowley knew making jokes was an asshole move. It was, and he acknowledged he might be an asshole for making them anyway. But the mood needed to be kept light enough that everyone had the energy to move on, otherwise they'd all be dead. So, after his silly little quip about smashing the mirrors had seemed to be taken seriously by the French were girl, Crowley turned to her with a smile between sheepish and something akin to 'I can't believe you thought I was serious'. "That was a joke."
She knew how to navigate mirror rooms, which was an odd talent to have but the best one for right now. Crowley for his part had never even stepped foot in one of these, though he had heard much about them. He was going to forget about the hand, but hopefully someone would remind him. It helped that they were all going the same place. When Sammy added to the right-hand rule with a left-hand one Crowley nodded. He began shuffling for a place in line when Kenna - who had been quiet and sullen ever since they had entered the funhouse, he noticed - suggested he and the French girl go first. Not only was that bullshit because she was going to be last, but also because he didn't want to be first! He was good at many things but navigating dark mirror mazes wasn't one of them and he'd rather be close to the one person he knew and actually kind of really liked in here.
He wasn't going to look like a cowardly douche, though, or delay them even more with hesitation. Making his way quickly to Kenna he renewed the protection spell - boy was that headache beginning to form - and after a second's hesitation planted a kiss on her forehead just because. Then he went over to the front, turning to Sammy. "If you have trouble with this because of your arm just call for me every once in a while, ok?" He refrained from adding 'please don't make me get lost I don't know what I'm doing' before signalling to the French girl with his head. "You probably have the better sense of direction, you go ahead."
