The fourth episode in the second season of Breaking Bad is a little bit on the slow side, but that doesn't stop it from being a great episode. This episode focuses more on characterization and mainly, the dwindling relationship between Walt and Skylar. This is a very dramatic episode, so don't expect many shockers or many action-packed scenes. The acting here is excellent and one is able to tell how about Cranston and Paul are absorbing their characters very well.
In this episode, "Down," Skylar keeps on leaving the house mysteriously and refuses to speak to Walt. Meanwhile, Jesse's parents kick him out of his house forcing him to be homeless.
Overall, this is a great episode despite it being slow and focusing on characterization. It's an important episode because we need to see how the relationship between the two is affected and it definitely adds to reality. I was not bored one single moment here. I rate this episode 9/10.
