"I've heard lots of Hollywood hearsay in my day, but I can only vouch for what I saw... here is one of the most fucked up things I saw behind the scenes of 'SBTB'. Draw your own conclusions because I still don't know what to make of it. "[Gosselaar] started getting called to [Engel]'s office for long meetings... and closed the door behind him. Which was weird... because typically Peter kept his office door open. "[Thiessen] also began to be summoned upstairs for long, cloosed-door meetings... then, both [Gosselaar] and [Thiessen] (!) were called together into [Engel]'s inner sanctuary for another mystery marathon behind closed doors. "[Gosselaar] and I were selected to go on a Paris [publicity] trip together... lo and behond, [Thiessen] pitched a bitch. She went up to [Engel]'s office for another hours-long, closed-door meeting, and when she re-energed it was suddenly her and [Gosselaar] now making the trip. "[Thiessen] wasn't even supposed to be around for 'The College Years'... all of a sudden, [Thiessen]'s locked again in those troubling closed-door meetings in [Engel]'s office and, voila, she's off to college with the guys. From then on the show's writing became all about Zack and Kelly."
