anyway, getting the thread back on topic
another miconception that I've heard a lot is that Jennifer Lien didn't know she wasn't going to be in the show anymore until she read the script for The Gift
If you look at the credits for Scorpion part II she is listed as a guest star. That involves a different contract and different pay scale. So I'm sure at that point she was made aware. Plus I would guess she would also have realized that she wasn't in any of the season 4 promo material.
