Distantly, Castiel registered what Sam was saying and it made little sense to him. He understood how to work the Internet only in the most conventional sense. Email...was another matter entirely, yet he realized he didn't have the heart to inform Sam that he didn't understand. "Do whatever you need to," he agreed. "If it helps."
His first inclination was to fly off, to go somewhere far away. Perhaps consume another liquor store, though that would likely be frowned upon no matter where he happened to go. He'd already apologized to the first shop owner he'd done that to. And drinking had only left him with a very sharp pain in the head of his vessel. Remembering how undesirable that was, he decided it would probably be best not to do that.
"I will use it if you show me how," he said, knowing it would probably be better simply to make amends. "But...if you say so."
Sam was mating with Veronica outside of wedlock, hence the term fornicating. He could have used the term 'copulating,' but that too would probably garner strange looks. It wasn't the time to argue. "It was not a jab at her honor."
Veronica was perhaps the farthest thing from Castiel's thoughts at the moment. Dean was gone and he'd allowed it to happen. He was not a guardian angel and never had been and yet, he couldn't quite get over the feeling that he'd failed. Both of them. Because it was impossible to fail one brother and not the other.
