I think the most common fanfic ship is Alicia with "Elyza Lex" (aka the Clexa fans from The 100 having a reincarnation AU ship, which I do get after how Lexa was killed off in The 100). There's some Alicia/Chris I think, but obviously he's dead now. I want to see new characters, and more importantly care about them.
I know! I actually punched the air when Shiva arrived in the finale! Screw everyone else, I am Team Tiger all the way!
