Castiel hadn't had any real intention of watching any of the fictional program he was supposedly from, but his concern for Dean and Sam has overwhelmed his reservations. He wanted to know that they were all right in his absence. He hadn't expected to see Gabriel siding with the Winchesters, and he certainly hadn't expected to see one brother killing the other. For all that Gabriel had abandoned his family long ago, he was still his brother. The loss was like a physical ache, moreso because it should never have come to that. If God had not abandoned his creation, Gabriel would have never had to die. Seeing the pain on his brother's face, he had almost sympathized with Lucifer. And that was dangerous. He wondered what this said about his faith and decided that he didn't care. He had given up everything, and it was all falling apart.
For now, it was not of consequence. He was trapped here, and he could not as yet change that. In truth, he had given up trying. It was an exercise in futility that left him feeling even more a failure than he had before. Joanna was the one spot of light in this place, though he had made connections to others, and he was glad for her presence. It made the weight in his chest seem lighter. She had been good to him, and not out of any obligation, and she had died too young. When he saw her, he didn't feel as though he had to force a smile or hide his pain. He didn't pretend. He just stood there, freezing up briefly as she hugged him, then hesitantly wrapping his arms around her and closing his eyes. Perhaps this, the funny sort of warmth he felt in his chest at the gesture, was why humans craved contact the way they did. It was...nice. "Thank you," he said quietly.
