"... Jeremy," he answers, at least a little relieved that there's someone he can trust here. He's not sure if he'll ever see her again after this, but it's a little sliver of hope he didn't have before when he first arrived. At the very least, he can try to look for her after all this. She seems confident they'll both get out of here. "I'll, uh ... t-try to look for you. After. If I-- ... if I c-can."
