So what if, and this is a crazy theory so hear me out, there's no hidden mystery behind the whole poisoning? It's already been spelled out for us in the narrative (Walt helping Jesse figure it out, we knew Gus was going to give a "response," etc.) Is there a reason this particular plot point has to be treated (by us) differently than every other?If that's the case and next week everything moves along under the assumptions that have already been made clear (but we never see a flashback to Gus or Tyrus poisoning the kid,) is this going to turn into a Sopranos/Members Only jacket thing that will be debated forever? I'm taking everything at it's face. I took the Gus thing at the end as Gus thinking about how Jesse said the kid was poisoned. That tipped Gus off. Ricin is undetectable, so the doctor's couldn't have figured it out (that quick, at least.) Jesse knowing it was poison means Jesse figured out the poison he was hiding was gone and figuring out it was Gus' response. But Jesse not accusing Gus outright and being pissed at him, was a tip off to Gus that Jesse was hiding something. He just put two and two together as he walked to the car. Then was just simply pondering the situation and what might be the next steps (for him and as well as anticipating Walt and Jesse's next move.) Then he was returning to the hospoital to confront Jesse, maybe?Maybe the whole "coincedence" of Gus not going to the car was just meant for dramatic effect, not to show Gus as omniscient.
