So I see. [ Cas almost chuckles - the war, the bombing, the arrival of his apocalyptically trigger-happy brothers. if anything, dean and geralt trading vulnerability may be some of the good news. ] It must have been a difficult exchange. I'm glad you found trust in each other.

[ trauma bonding, while certainly not the most healthy way to form relationships, has perhaps been the most prominent feature between the extended hunter family back home. makes sense dean continues to forge connection through it here. ]

Thank you, for... keeping Dean's confidence. For being a friend.

[ "looking after him" is really what cas means, but imagines there might be objection to that sentiment, either from geralt or the absent party in question. dean struggles without 'family' present. cas and geralt may not have been close, but he knew dean had formed a bond with him, knew he could be trusted. if anyone's likely to empathize with the harrowing aspects of their lives at home, it's geralt. ]

If I, um, ended up with any of your memories, I apologize, I must have forgotten it now.

[ geralt may be happy to have his business known by one less person, but it strikes cas as rude to just forget information so personal to someone. ]
