The "ricin cigarette" is probably one of the stupidest things in this
Yeah, spoilers for a show that ended 8 years ago.
Why would Jesse keep a stupid dangerous little thing in his cigarette packet all that time? I mean, wouldn't there be a danger of it contaminating his own cigarettes? It's ludicrous. This show fetishes certain items in a creepy way.
And it's ridiculous because they're acting like that's the only possible poison in the world so Jesse has to "hang onto it" or something. Walter could have made some more, and I bet Jesse could have figured out how to make some if he wanted to. I mean he made his own meth in the first place, which isn't easy.
In the episode where Jesse is about to "disappear" to Alaska and then changes his mind, it makes absolutely no sense. He already accepted the explanation from medical professionals that the little boy was poisoned by a common flower. And the child has recovered. Then he suddenly flies off the handle because something is missing from his pocket. Pure junk.
The only 'reason' he would run back and try to torch Walter's house is because they writers thought it would make good TV. That's it.
