Were he in his right mind, Nick likely would have known to stop. But, as he’d mentioned, reason had checked out long ago. He was just… angry. He should have been angry because of Lexie, but he felt like it went farther than that. He was still pissed off that they’d hurt Lexie, but now there was just something in his mind. Something that completely killed any part of him that may have been rational. He still heard Sarah and Wolf telling him to stop, and Rory’s anguished cries now permeated his ears, too. But no. He wasn’t listening to them. He couldn’t.
The next thing he knew, he felt something metal strike the back of his knees. “FUCK!” he shouted in pain, likely alerting the whole apartment complex, and swung his arm back, connecting with his aggressor and shoving backward with all his might, not realizing that he’d inadvertently broken Lulu’s other rule. And after that, he resumed his attention to Eisen.
