It's just awesome because they are both equally proud of the other. I dint see Destiel much. What I see is a guy who slowly realizes he loves someone more than his brother. Not as a lover..much more than that..someone who he trusts more than Sam or Bobby. Someone who stopped at nothing for this insecure human. Someone who..to his surprise..made him feel worth don't for (multiple times). My conclusion: Castiel is legitimately Dean's guardian angel.
