It looked like it was in a potter so I'm guessing Walt recently bought it to poison the kid
Jesse did ask Saul to do that for both Kaylee and the boy that Todd shot. Saul says it's a bad idea becase giving money to the Sharp(?) family would only raise more questions and wouldn't shed light on what happened to their kid. Saul also points out that everytime Mike has left money for his granddaughter, the feds have gotten it, so Jesse leaving it for her would probably end the same way)
Schadenfreude? :)
The nurse spelling out "fuck" for Hector was hilarious. By the time you get to "c" I think most people would stop but not her until the feds stopped her she would have kept going. She's a true professional
The gas tank had a bullet hole in it. We saw Walter on his hands and knees looking at the ground and then saw him look at the outside of the car and at the gas cover with a bullet hole in it
