He flinched slightly as the benches twitched and pulled against their holdings and he shifted slightly as the pain subsided.

"I didn't tell him." He told her, which was the truth. He hadn't told Dean where she was when he'd found her. He had left the gps on his phone on but she didn't need to know that part.
