quote: Looked like Megatron is gonna be the main bad guy this season. I'm guessing Crowley will be the final bad guy next season.
I hope not. I know they had a story arc for the final 3 season when they were announced like they did for the first 5 seasons. I feel more confident with them having something in mind. I like Crowley but he's been a bad guy for like 5 seasons now it seems.
I assume Crowley's been around so long because they're building him up for something big. My prediction is Sam and Dean will need his help to kill Megatron but he'll screw them over and get more power leading into season 10.
