AJ was fairly sure that Mari was the only reason he was even here considering most of these people weren't exactly his sort of group. Then AJ's friends were a scattered bunch from all sorts of backgrounds and they had all formed some sort of soft spot on his usually hard exterior. Even when they were driving him crazy, he'd still do about anything for them. Though the crazy driving was usually his sister and he was honor bound to love her regardless of anything she might say or do. Mari was really just a sweetheart of a girl that he rather liked helping out. She was just cheerful which wasn't something he saw a lot of...
His brain was going about a mile a minute though trying to figure out the tone in Mari's voice before she left and the other motions as she headed off to the bathroom. Olivia's question was just the perfect opportunity to go and at least see what was going on without feeling like a creeper hanging outside of the women's bathroom to make sure Mari was okay. "Yeah, I should probably make sure I give Mari her gift before I have to go." Dancing wasn't really his thing, but something messing with Maribel Santa Cruz's general happiness was worrisome.
He went along with Olivia, keeping a half step ahead though so Bailey wouldn't start thinking he was checking out his girl... Hell, Olivia probably had mace on her if he even glanced in the wrong direction.
