Andromakennethamblesorton Parcell, better known to many 30 Rock fans as Kenneth the Page, was the lovable punching bag of the cast and crew of TGS with Tracy Jordan. While he started out as the resident goon, his character went through some big changes throughout the series, and that doesn't include being all but revealed as an immortal. Plus, a Season 1 episode predicted two major future ups and downs in Kenneth's career.
When the series first introduced viewers to Kenneth in Season 1, Episode 1, he seemed like the walking embodiment blandness. The long time member of the NBC Page Program was more or less devoid of personality. However, over time, Kenneth was revealed to be far more cunning and intelligent than a lot of fans would have originally suspected.
The first hint of this came in Season 1, Episode 3. Jack Donaghy joined the weekly writers poker game to find that Kenneth was the only person he couldn't read, as his lack of personality played to his advantage. Eventually, Jack was able to defeat Kenneth and learned a lot about the "young" Page in the process. Towards the end of the episode, Jack even remarked about Kenneth, claiming "In five years we'll all either be working for him... or dead by his hand."
This was echoed later in the same season when Jack's nemesis Devon Banks made his first appearance in Episode 18. As the two executives began one of their verbal jousting sessions, Kenneth showed up. Jack joked that Kenneth would eventually take Devon's job, Devon said Kenneth would take Jack's job, and Kenneth pointed at a nearby Janitor and said he would take his job.
Little did everyone involved in the conversation know that they were pretty much all right. Moving on from the Page Program, Kenneth would eventually take a new position in Standards and Practices only to give it up to help Tracy. In Season 6, Episode 14, Kenneth was trying to find a new position at NBC and ended up becoming a janitor, holding that job for virtually the rest of the series.
Then in Season 7, Episode 11, the unthinkable happened. After being named the new Kabletown CEO, Jack needed to select someone as his successor as President of NBC. He enlisted Kenneth's help in an unintentional homage to Charlie and the Chocolate Factory as means of testing possible candidates. Jack eventually gave the job to Kenneth, which the series finale revealed he still holds decades in the future.
Pretty much all the predictions laid out for and by Kenneth in Season 1 came to fruition. He spent several episodes as a janitor and then leapfrogged all the way up to being the President of the company. Fortunately for everyone Kenneth worked with, Jack's alternative prediction of the former Page killing them all never came true.
