[he already looks apologetic, even before he starts to speak. he hadn't wanted to hide any of this. but he'd known, at the time, that it wouldn't help. that until castiel had recovered, telling him about lucifer wouldn't change a thing.

and so he'd just...kept it to himself, despite how uncomfortable it had felt. sure, it wasn't a lie. but an omission isn't that far off.]

It was about two weeks ago. I didn't...ask to talk to him. I just- I went to sleep. And then he was there. He said that Sam told him about me. So he wanted to...meet me.

[he frowns a little at that. at the idea of sam having told others. of having told lucifer, of all people]

I don't think he knows what I am. He knows that Sam's...taking care of me. But he doesn't know why. I...didn't tell him.
