If they were trying to be threatening, it wasn't working in the least bit. Luke could already tell none of them had any clue how to fight which put himself in the clear advantage. Olivia brandishing a knife raised the odds of them being the victors that much higher.
It took all his manpower to not rush forward and take care of the other two, reminding himself he wasn't home anymore and he didn't have a ton of guys for backup. Still in a more defensive position, he waited for the idiots to make a decision. Wisely, it seemed they chose the latter in the Fight or Flight survival tactic. However, the alpha chose to let off a very real parting shot that left Luke sighing and running a hand through his hair. Great, the police yet again. Although it didn't stop him from shouting after him, "Oh Mick, real original dere!"
"Well ye held yerself up back there," he remarked to Olivia. Stretching his arms, he continued talking. "What do you tink de odds are he will call the police? Ten dollars is me claim I get arrested before ye," he said lightheartedly. He didn't even mention the knife as he figured it was better not to antagonize her while she was already in an excited mood.
