It had been a month since Dean had heard anything about Castiel, every day he would worry more and more about the angel, he was beginning to get angry at Cas for not coming back, for being such a child and not realizing that Dean was just stupid for saying what he did. But Dean wasn't angry for long because he reminded himself that the reason Castiel was because of what he had said to him. Dean never tried contacting the angel, he took Castiel's words to the heart not wanting to show Cas that he did actually need him and letting his pride get in the way made the situation even worse.
Sam on the other hand prayed to Cas constantly every day before he would go to bed he would go inside the bathroom of whatever motel they were in and prayed for him to please come back, he would tell Cas that Dean was hurting and that he was sorry for what he had said, Castiel never came he never even gave Sam a hint he was listening but he still prayed to him because he felt bad for his brother and he really wanted to make sure Castiel was ok, where ever he was.
Back in heaven Castiel would sit alone in whatever part of heaven and see what the Winchesters were doing, he needed to make sure they were ok because they were still his responsibility, all the other angels were glad to have him back, they all kept telling him that he was spending too much time with the humans and that they were happy to see him every day back where he truly belonged. But Castiel no longer felt he belonged with the Angels in heaven, he wanted to be with the Winchesters keeping a close eye on them, not like he was doing now but like before interacting with them having Dean say some joke he couldn't understand and watch Sam sit around on his laptop, that's where he felt he belonged, but the way Dean had spoken to him made him very angry because no matter what Dean said if Castiel was by his side he would always try to protect him and he couldn't understand why Dean threatened Castiel by saying that he would kill him. It made him angrier thinking about it, he would hear Sam's prayers at night but never go down, he thought Dean needed to learn his lesson because lately he felt as if he was being taking for granted for being an angel and not a friend.
