Richard was relieved to feel her move towards him. It meant that she didn't completely hate him. With her shoulder against his he could feel her shivering,and he couldn't sit by and let her be so miserable. Cautiously he put his arm around her shoulders. "I've got enough body heat to share." he mumbled. Hopefully she wouldn't freak out and shoot him or anything.
Rin let out a long breath and leaned her head against his shoulder, her hands resting on the rifle laid across her lap. "You aren't allowed to die, okay?" She said plainly, her eyes looking up at him. "I won't be able to go on if you - just don't die." She continued then sighed. She felt bad about what had happened to Cas, it really was terrible, but the thought of it happening to Marcus was more than she could handle. He was her world, and without him she'd be nothing.
