Bowdz said:Insane episode like usual. Easily the best written TV show out there right now.
As for who poisoned Brock, it seems incredibly unlikely that Walt did it simply because of the time frame of the whole situation. I honestly have a hard time piecing together when Gus would have been able to pull it off, but it seems more likely with Tyrus on hand.
I have to say though, after hearing Bryan Cranston's words about the finale and Giancarlo talk about tonight's episode, I honestly think Walt might have poisoned Brock.
"At the very end of the season, there are a couple things that happen that are really surprises. One is the big surprise. Then, 'Woooow!' A big wow moment. Then you calm down and there's a bit of a tag to resolve a couple issues, and then, just before it goes black and has Vince Gilligan's name, there's one more little thing. No words, just a visual that the audience will see and it will have the reaction, 'Nooo! Oh, my God!!! No!' It will rock you. Then it goes black and that's the end of the season." - Bryan Cranston
I think that Jesse and Walt end up killing Gus and then the finale "little" thing before the end will be a cut of the ricin cigarette placed somewhere in Jesse's stuff indicating Walt killed Brock on his own.
oh god how much would people rage if that little "visual" was actually the esposito/gus spoiler pic haha
