Fenrir didn't speak Spanish per se, but one of his pack mates when he'd been younger had spoken it, and he'd picked up enough to get the basic idea of what she was saying, which stoked the fire of his anger. Maybe he had promised not to kill her, but he didn't want her to just think she could do whatever the fuck she wanted to either. It was clear a few ground rules needed to be set, so he stood up and walked towards where she had moved to.
He grabbed her shoulder roughly and spun her around, then back handed her, knocking her over. "You listen here, I might not kill you, but you have to stay in line or I'll stop keeping my boys from you, and I don't think you'll enjoy their idea of 'fun'." He litterally growled at her. "Eat your fucking dinner or I'll stuff it down your throat." He stalked back to the other side of the fire and leaned against the wall, lighting another cigarette as the first one had been dropped in his anger.
