They thought up a Borg Characer.
So they had to fire someone to make room in the budget.
They said lets fire Wang, he's bloody useless.
However between the airing of Scorpion one and two, during the months long hiatus break, somehow Garret Wang was placed on People Magazine's 50 Most Beautiful People in the World Yearly Poll, which back then was a really big thing...
They couldn't fire Wang now, and they still wanted to hire the sexy Borgette.
So they fired Jennifer.
