Hartley looked at Cisco, eyes wide, but he clearly trusted him. Even as he put headphones on him and especially when he turned them on. Not perfect, but silence. For the first time since the explosion, there was blissful silence. Hartley smiled, watching Cisco's face and trying to read his expression. He whispered, afraid he might shout otherwise. Volume was difficult to judge. "Thank you."

He didn't even think now, he just reached out to put his arms around Cisco, eyes closing as he pulled him close. He had been so scared. So alone. All alone, until he remembered how to reach out to Cisco. "Thank you for coming."
