I am guessing Hank gets killed in the shootout. That last conversation he had with his wife was a giveaway. Also when Walt went to his old house I thought the neighbor lady was more in shock to see Walt than scared.
I wasn’t watching BB much when Brock was poisoned by Walt. Why did he do it?
He was trying to turn Jesse away from Gus Fring. Gus had decided to kill Walt and he was having Jesse do all the cooking. So Walt had to make Jesse think that Gus poisoned Brock.
I THINK (and I am not sure if I remember it all correctly)
Walt has Saul’s guy lift the cigarettes from Jesse, then gets Jesse to think Gustavo Fring did it. He did this because he thinks Fring is going to bring Jesse over to his team and kill Walt.
But then we find out Bronk is not poisoned by Ricin- but by an extract of the plant “lily of the valley”. This is a little bit of a disconnect for me- They show Walts house at the end of that episode and show a Lilly of the Valley plant... but now they act like it was ricin... I dont know...
