I think Jesse does Todd's uncle and his gang in with Science,Bitch!
First season,Krazy 8 and Emilio get poisoned due to a chemical reaction that Walt concocted inside the RV. Fast forward to earlier in the season when Todd starts making his own batches of meth and he advises his uncle and the crew to put their masks on and they say they didn't need to. Now Jesse's being forced to make meth with Todd and with Jesse trying to escape and Andrea being murdered,everyone's gonna be keeping a close eye on him now. Jesse and Todd will be the only ones wearing the masks and Jesse will recall that day in season 1 and will do the same thing poisoning everyone except Todd. Somehow Jesse will overpower Todd and escape.
Many things to cover in the last 75 minutes of the show but I just wanted to add another element to the discussion.
I collect Albert Pujols,NY Mets,Topps sparkly parallel sets and golf.
