Castiel

*you were with Castiel, talking to him. he was talking to you, using a clueless voice to sound cute. you were talking about hunting and explaining it to him. when somebody suddenly interrupted and started to talk to you. Castiel immediately felt a cold sense of jealousy. like he had to scare that person off for even looking at you. you didn't notice Castiel being angry since he still had a smile on his face.*
