What do toi think happened between Dean and Castiel at the end of "I'm no angel"?

Personally i don't think Dean would have explained it, he might have a dit that it is for the safety of Sam since he is still very weak and since Cas don't have his powers he wouldn't be able to fight off all the angles alone. Plus if Cas knew then there would be a greater fear of Sam finding out and Dean would never risk that.

i think dean could have explained things to castiel because cas would understand and knows sam is important to dean but i think it would have been very hard for dean to make castiel go

i hate zeke for making dean get rid of cas because i wanted to see plus of him as castiel is my seconde fave character after dean who is my fave
