Spoiler So... I think I've got the whole ending figured out. I was half right. I always knew Walt would be using the gun that we saw in the S5 premiere last year to mow down a bunch of bad dudes. Once Todd and his family came back into the picture this year, I figured the gun would be used to get rid of them. After having seen the latest episode, I would say that this is correct, but that Walt does it all to save Jesse somehow. Maybe Jesse ends up being forced to help cook with Todd's family, and Walt eventually comes back for him... probably dies in the process of saving Jesse. But what about the ricin?!?!?!?! Ahhhhh the finale is going to be a masterpiece! Did everyone hear how they're doing a prequel to Breaking Bad with Saul as the lead character? It's titled "Better Call Saul" as of right now, but I think that's a bit lame. I think Saul is best in small doses, so I'm not sure how well this will work out. I would rather them leave the series be and let BB stand alone in TV history... I'd hate for a failure to be linked to it. I don't think Vince Gilligan is the primary writer of the show, but he is supposed to be involved in some way, so I do have faith to an extent.
