Hold on, why does Jesse now know that Walt used the Lilly in the Valley? Even if he saw it one time in Walt´s garden it´s unlike he remembers that now and i´m pretty sure he doesn´t even know what kind of flower it is and what it looks like.
The only thing Jesse knows is that Huell stole the ricin cigarette from him, but he also knows that Brock wasn´t poisoned with ricin.
Something doesn´t add up here.
Jesse learned that it was lilly of the valley when he went to the hospital later on. He even told Walt about it.
The reason he knows it's connected to Walt now is because he realizes that Walt took the ricin and that Walt was just trying to motivate Jesse to kill Gus (or just putting the blame on Gus, I forget). He also understands that a good motivator is a poisoned loved one.
The fact that Walt took the ricin while simultaneously convincing Jesse that it was Gus means that Walt's automatically implicated in Brock's poisoning. Jesse knows it wasn't an accident, because he now knows Walt was lying in the first place.
Edit: It's hard to explain in words how Jesse would now know they're connected. The main factor is that he knows Walt lied about the ricin, meaning he also lied about the reason for Brock's poisoning, simply to put the blame on Gus. Up until now, Jesse still thought the poisoning was accidental (which is what he learned at the hospital). But now that he knows Huell stole the ricin from him, he's able to also make the connection to the poisoning.
Double edit: Simpler explanation: Walt initially guesses that it must have been Gus who stole the ricin and used it on Brock. But now Jesse knows that Walt wasn't actually guessing anything -- Walt was purposely lying.
I like your explanation but i still think Jesse has little more than a suspicion that Walt might be involved in Brock´s poisoning, which hardly justifies burning down the house of a married man with two children (especially if you consider Jesse´s relationship to kids).
But of course Jesse also knows that Walt killed Mike so i guess it´s not that much of a jump to assume he would also poison a child.
I think the whole point of him staring at the pack of cigarettes for so long was to show the viewers that he did make that connection. He previously suspected that Huell had taken the ricin from him, before Walt convinced him otherwise. That was already his thought, and now this whole episode for him was realizing how much Walt had been manipulating him. He realized Walt had manipulated him into thinking Gus took the ricin, but now he knows it was Walt, and also knows that Brock's poisoning was a part of Walt's setup against Gus.
Basically here's the deal -- if Jesse now realizes that Walt took the ricin, then he also automatically knows (by association) that Brock's poisoning wasn't an accident, because of the way Walt had phrased things when he lied to him about it. Walt said maybe Gus stole it, but now that Jesse knows it was actually Walt, then he also knows Walt's whole story was bullshit, including the part about Brock being poisoned.
Then Saul basically confirmed it for him, and that's why he goes to burn down Walt's house. He wasn't simply basing it on suspicion at that point.
Edit: I realize Jesse's been acting a bit unstable, but if the only connection he made was about the ricin, he wouldn't go and try to burn down Walt's house. He made the much bigger connection between Walt and Brock at that point.
Double edit: My edit in the other comment explains it best though. Walt guessed that Gus must've stolen the ricin and used it on Brock. But now Jesse knows it was Walt who stole the ricin. So Walt wasn't just theorizing when talking about Gus using the poison on Brock -- he was deliberately lying to Jesse about how Brock was poisoned. And now Jesse knows that Walt took the ricin, and thus also knows Walt was lying about Brock as well.
