Lex always had a knack for sensing danger, he would feel the hairs on the back of his head stand. But he'd obviously sensed too late, there wasn't much to do before he could hear Jace's voice, "Turn around slowly, Lex." The smile on his face dropped. The only thing he could think was 'What's Jace doing here?' as he turned to see Jace aiming a gun at him. Ev wasn't far behind her brother, telling him to put down the gun. Lex swallowed slightly, knowing very well that being related wouldn't stop Jace from pulling that trigger. "Kitty, I want you to duck and hide, go inside if you have to. But don't call the cops." He spoke lowly so only his friend could hear him, never looking away from Jace. He slowly opened the door to the car to step out, able to hear the fighting in the distance, "Jace, what're you doing?" His voice was just as authoritative as Jace's, but managed to have a warm, caring feeling in it. Lex could feel the gun in his jacket, it was rare for a Montague not to have some sort of weapon on them, but he didn't want to- no, couldn't pull his gun on family. "Listen to your sister and put the gun down. Please." Lex glanced over to the house, from the music that could be heard even from where they stood, it was likely that a gun shot would not be easily heard. He couldn't help but be relieved by the fact that if Jace did shoot at him, his cousins would probably manage to get away before anyone called the cops.
