Dean was shocked by the desperation in the angel’s voice when he asked what he could do. He opened his mouth to answer but quickly closed it when he realized he didn’t know the answer himself. He frowned as he thought about it. He realized that Sam must have thought Cas could help otherwise he wouldn’t have contacted him. He stared at Cas knowing that he wanted an answer, “Just be here,” he told him, shrugging helplessly, “That’s what you can do, that’s what I need you to do.”
Castiel stared at Dean after he told him what he could do; he could tell what he had just admitted was a big deal so he didn't want to say the wrong thing. "Just be here," he repeated, nodding, "I can do that," he told him, taking a step forward, "If that's what you want me to do."
