She pulled her lips into her mouth to fight the laugh that would have tumbled out because of his reaction. She wasn't sure who's was more priceless; his or the fan girl she was about to make sodding mad.

She raised one brow, peering past Nick at the girls. She was going to hell for this, she knew it. She was going straight to hell for what she was about to do...but it would be worth it to see that bird's reaction.
Elisabeth slid out from the booth, towering over the kid in her 5'11 body, but still finding a way to wrap her arm about his waist, placing a lingering kiss to his cheek. Her glance over her shoulder was short enough that he'd likely miss it, but long enough that any crazed fan girl would catch and know. She had openly claimed this underaged Jonas as her own. "They're meeting us there, I already texted them. It's going to be so fun!"
She quickly lead him outside, only letting him go when they had left sight of the windows and such. "Oy, sorry about that, yeah? She was just too much fun to brass off." Elisabeth chuckled to herself, offering her hand. "Elisabeth Braddock, love. Your brother's a fan, needless to say. I'm an X-Man, s'why I could use telepathy on you."
