7. Beric Dondarrion/The Brotherhood Without Banners
The Lightning Lord and his band of misfits essentially already have their own spin-off. We just haven't seen it on screen until recently. Beric Dondarrion (Richard Dormer) and The Brotherhood Without Banners have only been in a handful of episodes in season 3, but they have given us some of this season's most entertaining moments. We learned that the Brotherhood was formed after Ned Stark and Robert Baratheon died, in an effort to fight for the small folk and protect the countryside. Since its introduction, we've already seen Beric magically light a sword on fire, get killed in an epic battle with the Hound and get resurrected by Thoros of Myr via the Lord of Light. And Beric is totally nonchalant about the fact that he's been brought back to life five times beforehand. You can't blame Gendry (Joe Dempsie) for wanting to stay with the Brotherhood. They like to drink, shoot things with arrows and they live in a giant random cave. Seeing the Brotherhood fight for the people and anticipating which way Beric Dondarrion will get killed next would be an entertaining show in itself.
