Drew couldn't fire Bart, and that's not what KenCrane said anyway. KenCrane said Drew probably had something to do with it, which I take to mean Drew may have had his henchman do the deed. Note that there was not an orderly transition between the two directors, so what does that tell us? As for KenCrane, he apparently works in the building and relates what he sees here, which is sometimes at odds with the made-up fantasy that gets posted by people thousands of miles from Beverly and Fairfax.
Pentellit has said little if anything about Barker in this thread, which was set up to discuss her claim that Goodson was bedding down Dian, yet the usual suspects are jumping down her throat.
So if, as you state so emphatically it WAS Drew, I wanna know who's saying that.
KenCrane! See above. He/she also says no one likes the new guy, which is consistent with what I've heard from people in the building.
