"Bug" is the episode title and what bugged me about this episode was how they randomly brought back Skyler's work as an accountant. Has this even been addressed since last year? I don't recall, and I don't know why they felt the need to have it here, unless it will lead to her making another mistake at the car wash and someone finding out what it is really going on. So, I would like to believe that it is foreshadowing, but my head is also telling me they were just trying to find something for the stagnant and annoying character to do this week.
But this episode was made by the fight between Jesse and Walt. It was funny, it was dramatic, it was believable to an extent and just showed how great this cast is and how far they are willing to go to entertain the viewers....I know I was.
