Hunter bites his bottom lip when Jim grabs him. And moves forward to gently wrap his arms around Jim. "I'm here. I am not leaving..."

He wants to promise that he would never leave. But he doesn't know what Jim experienced in the Nightmare. Did someone else make that promise? Did someone else leave?

So he just keeps that promise in his heart, while he embraces Jim gently. Letting the shower wash over both of them.
