"I see." Castiel takes a moment to think about this. He's not sure why the man would take it so personally. He knows he's seen the two of them together since then and they seemed fine, but if it means so much to Anna, he supposes he can extend some sort of formal apology.

"I'll speak to him, Anna. I didn't realize that he was so important to you." That, at least, he understands. It's good to see Anna happy, especially after what they had turned her into towards the end. This isn't quite the Anna from before and he knows she won't be commanding him in any battles, but she's an Anna he wants to see more of. Having a sibling he can care about without an entire train of baggage is nice.

He smiles a little. "There won't be a repeat performance as long as you don't want there to be one."
