What does Her character was written out mean?
On That '70s Show, the veteran actress played the promiscuous elder sister of Topher Grace's Eric Forman for five years. Her character was written out, though Kelly returned for a few episodes in Season 5. Then, she was replaced by Christina Moore in Season 6.
I assumed a number of things but I can be sure to be wrong in each case. It doesn't make sense if it relates to writing down individual letters.
