The ATM that Hank used to get the pictures of the RV that Walt and Jesse used to cook meth is the same ATM that was used to kill Spooge (the man who helped to steal meth from Skinny Pete). The red blood can be seen on the bottom of the ATM in the scene.
The gas station cashier tells Jesse "my dad's a hard ass," which is what Jane told Jesse about her dad.
The oldie Walt is listening to on the radio in the very last scene is, "In The Valley Of The Sun" by Buddy Stewart.
Hank tells Gomez "don't hate me because I'm beautiful" which is a quote from a Maybelline commercial starring model/actress Kelly LeBrock.
