Jackson wasn't perturbed per se, at least not at that moment, but he was very curious about what was going on between Keiran and Sam and wondering if he should leave the two of them alone. With Sam, he didn't feel that brotherly level of protectiveness with Keiran as he had with others. Sam was safe, he was like them and there was no need to protect Keiran against him. Disarming, that was the word to describe Sam.
"It's busy but it's not that busy. It's not like the owner cares much anyway," Jackson spoke up, but nevertheless gave the bar a quick once over to see if his words were right. And he had been right all of three seconds before one drunk threw a fist at another knocking the both of them on the floor. "Excuse me."
His face lighting up with glee, Jackson waded into the crowd that had gathered to watch and hauled the two men to their feet, one by the scruff of his collar, the other by his beard. Using his large bulk, he hustled the two men out the door, disappearing outside a few minutes to toss the drunks and threaten them with dismemberment and bannings if they didn't behave in the future.
He returned a short time later and settled back in the booth. "Sorry about that. I guess we should get back to work eventually hm?"
