As I said, Jesse has a good heart. I'm not going to argue about that, though.
And If you can't see that Walt cares deeply for Jesse, even after all that's happened, you might be watching a different show. Just look at the scene when Skyler suggests Jesse should be killed. Walt says "Jesse isn't just some....thug. He's a human being." I'm sure I'm getting that wrong, but I know he defended him. If you can tell me someone (alive) who cares about Jesse's well-being more than Walt, enlighten me. Walt only put the hit out on him for the good of his family. And who knows if he would have let it happen anyway.....
Walt and Jesse have a deep, deep bond. Something tells me in the next 3 episodes, that will be obvious to a lot more people.
