I think you guys are taking Pete too literally. He banished Marty for long stretches in late January and late in the season. He's just saying what he has to say for public consumption because let's face it, Marty's still a lot more popular than Pete. You're not going to get anywhere publicly ripping Marty, no matter whether it's true or not.
Personally I'd be a lot more worried about what Lou says/does vis-a-vis Marty than Pete.
