4. Walt Kills Jesse and Hank
Walt killing Jesse is more likely to happen then Jesse killing Walt. At this stage of the series, A LOT has been revealed and Walt knows he's in trouble. In the debut episode of the season, Walt is seen going back to his old house to retrieve the ricin he left behind. There's a strong possibility that Walt will use it to kill Jesse, Hank and any other loose ends that tie him to being Heisenberg. As we all know, Walter White will NOT go down without a fight. Through out the series, he's proven time and again that he's willing to do whatever it takes in order to get what he wants. Hank and Jesse now pose as Walter's greatest threat of getting caught and serving the rest of his life behind bars. I think we all know that's a highly unlikely outcome. Which means someone's got to go. Whether it be Jesse, Hank or both, I just can't see them all surviving until the end. Like I said, the finale is going to get intense.
