- When did Walt tell Saul and how did Saul poison Brock?
- At the hospital when Brock is sick...did Jessie still have the "cigarette" on him? If I remember he was missing it. If Walt wanted to implicate Gus, why did he need Jessie to be missing the cigarette?
- Just as Jessie is about to leave with the vacuum guy, he takes out a pack of cigarettes, and after fiddling with it he clicks that Walkt poisoned Brock. What is it about the pack that allowed him to put the pieces together? Or is it because Yule was able to steal his dope from his pocket?
That whole string of events is unclear to me.
		
		
	 
Huell took the cigarettes from him, but Walt was the one who poisoned brock. Saul said as much when jesse figured it out.Jesse didn't have the cigarette in the hospital. When he saw brocks symptoms he flipped out on the cigarettes in his pocket and yelled no with a handful of ripped paper and tobacco. He thought walt had done it, and went to kill him, pointing a gun at his head.
Huell stole the weed from his pocket when he left the office after saul told him not to take the weed with him and jesse ignored him. When jesse realized huell was a skilled pickpocket, he realized that it was way more likely that walt had asked saul to steal the cigarettes than that gus had done it.
