Does Dean know Castiel is the one who let Sam out of the panic room in When The Levee Breaks? If so, how and when did he find out?

I don't think he does. Same as the voice-mail thing. :/

Which still breaks my heart.

It's never mentioned again in canon, so presumably neither brother knows about it.

My head canon is that they both kind of know. Ruby couldn't have done it, and Cas had made it clear he was back on Team Heaven. But Cas was obviously acting under some degree of coercion, and he had a change of heart and died for them immediately afterward, so they decided to let it drop.
