There are rumors that Downton Abbey will only have one more season. We are expecting a kick-butt finale. There are also a few plot lines that have been introduced along the way that need some closure. It’s a rule of writing that whatever is promised in the pilot should be sufficiently wrapped up in the finale, so as not to upset your fans. I need only mention Lost and How I Met Your Mother as examples of finales which left the fans angry, upset and frustrated. So this is how I would end Downton Abbey:
1. Thomas will pull another grand scheme to hurt Mosely. It will backfire in his face and he will die a slow, horrible death.
10. The true heir of Downton Abbey, Peter, who was believed to have died on the Titanic in the pilot (and who showed up in season 2 with a mangled face) will return to Downton, having undergone plastic surgery. He will then marry Edith, who will then inherit her father’s portion of the estate. Due to some legal mumbo-jumbo, Mary and her son will lose their share of the estate also, and Edith gets everything.
Season 6 is probably already written, and mostly filmed. But I wouldn’t be surprised if at least a few of these ideas showed up.
In fact, I expect it.
