oh hey dude my bad i must have missed the visitor message but my favorite quote is probably in season 5, when walt, mike, and jesse are looking for a new place to cook. they discover vamonos pest, and mike says "should we take a vote?" and walt, like a cocky douchebag, replies simply with a smug "why?"
honestly any season 5 walt quote because he's such a terrible human at that point it kills me
