Can someone please explain to me the ricin and lilly of the valley thing? This is what I know:
- Walt produces a ricin capsule so that Jesse can poison Gus.
- Walt tells Saul to have Huell steal Jesse's cigarette pack to make Jesse think that it was Gus who stole it & poisoned Brock.
- Turns out that Brock was poisoned by Walt via Lilly of the Valley.
- Walt & Jesse find the ricin cigarette in that Yoomba thing.
- Huell steals Jessie's dope & this reminds Jesse of the other thing.
1. So, how did Huell steal Jessie's cigarette pack when Jessie already had it on him & found out that the ricin cigarette had been stolen? Or did Huell only lift the ricin cigarette & not the whole pack?
2. How did Walt even meet Brock to get him to consume the Lilly of the Valley thing after Jessie told him to stay away? Also, did he use some powder or liquid from that Lilly of the Valley thing?
3. How did the ricin cigarette end up in the Yoomba? When did Walt put it there if he did?
Also, are these questions even important or am I just asking useless irrelevant questions?

I really wanna know these things to understand stuff better and explain it to my friend.
