Yes. I agree, Skylar is looking out for her families best interest here.
She is clearly fucking with the books at the car wash, which was shown, and if the IRS comes at her, and examines their story as to how they got the money, their story about gambling with come crashing down.
I am wondering if Jesse turned on Walt completely, and if part of the meeting between Gus and Jesse wasn't shown. Why would Jesse all of a sudden now, be asking for more details on cooking, if he wasn't trying to come through for Gus.
Who knows, that's why this show is so great.
