Once her fist had connected, she'd been hauling back for another hit, but then Church had spoken and she'd jerked her head to the side to look at him, eyes widening some, then she looked back at the blonde Spartan, who was stumbling back a step.. then he opened those bright blue eyes and he stared at Tex for a single heartbeat before he jerked forward and swung his own fist up into her jaw-- but he didn't stop there, he kept coming, and he'd run straight into her and tackle her to the ground and grab a fist full of her hair and haul it back before he hit her in the face again. Tex, who was too startled at first to do anything, was able (after that second hit) to jerk up a hand and grab for his wrist, but he was landing another punch seconds later.
"RIVER!" Tex screamed the girl's name out, because if York didn't stop soon, she was going to break his neck out of self-preservation.
