"Shopping it is," she nodded, turning to inform Longshot, "You're in luck. Rover gets more excited about shopping than anyone I know."
She gestured toward the speaker as Jack explained that he had sniffed out the fact that Longshot wasn't a mutant, waiting until he was done to ask questions about Rita... who it sounded like Longshot had left behind very recently. Domino made a mental note to call in a favor and have someone check arrest records on Red Light later, just to make sure that nobody by that name had been apprehended. First, though, there was a very non-scientific experiment to be done.
"Cup and jog," Domino suggested, flipping the coin and catching it repeatedly as she waited for Jack to join them. She smiled at Longshot and answered his question, "Coin toss. 50/50 chance. Just testing this 'luck' thing of yours."
As soon as Jack's footsteps were within earshot, she announced, "Longshot called heads, I have tails," and flipped the coin up higher into the air, stepping back to keep herself from bumping it and possibly influencing the results that way.
