I was reading a rumor/spoiler site and they were theorizing it was Rick that kisses Lucille the season finale. I just have a hard time thinking they kill him off. I think it will be someone involved in a relationship. My money is on Michonne. Here is why I say that. Think back to that scene with Rick and Abraham with Abraham asking Rick about this world when you have a partner you care about. Forgot the exact dialogue but Abraham saying he was not ready to rip the world a new asshole. I think Michonne dies and that takes currently hard core Rick into uber hardcore Rick and the first half of next season is him plotting to kill Negan to exact revenge with the mid season finale being Rick killing Negan in some horrific manner we can't even fathom right now.
