Her smirk turned mischievous when she heard the different tone to Becca's- no, Ruby's- laugh, but Jax didn't comment. She wasn't really threatened by Ruby in any real sense, and trusted that if it came down to it, she and John could handle the demon until Becca got a hold of herself.
The question of 'now what' made Jax feign shock. "What do you mean, now what? We're in the middle of a bar, surrounded by beautiful people, and about to be drunk. Now? We dance," She slid off the barstool, sliding a bill under her glass to cover her immediate tab (so she wouldn't forget and be harassed like last time), offering an arm out to Becca to lead her to the floor.
