I've got a Bakewell heart

"Misha Collins makes his first appearance in Season 8 as Castiel. It may be brief and all in Purgatory flashbacks, but they are emotional. He is subdued, more like the old Castiel than he was in the later half of season 7. Collins makes sure to connect with Ackles while on screen, showing us in body language and voice that Castiel still cares about Dean—-even if we’re being led to believe that he abandoned his friend. He has remorse painted in his facial expressions. The fear and desperation we’re left with in the final scene leaves us heartbroken—-and Collins sells it with the pleading in his voice."
