Before season 10 I really want to watch all the previous seasons again. To be honest, I also don’t know if I am strong enough.
* aggressively still pissed off about the way in which abaddon was killed *
I think season 9 had too many big bads and too many storylines and Abbadon suffered from it. I mean, there was the angels being on earth and shut down from heaven, human Cas, then graceless Cas, Metatron, dying Sam, Gadreel, Crowley being a human blood addict, Abbadon, Dean and the first blade/Cain’s mark, Sam and Dean issues with each other… For most of the season, all of those things were happening at the same time and you couldn’t exactly say what was more important. Then it was the end of season and they had to resolve everything and it got way too fast…
