I can’t remember his real name but when Scott found out about it he made her leave the show immediately…THAT day. They had to do some writing around her until they got her replacement.
The actor that Missy had the affair with is Jason Brooks, who played Peter Blake on the show. At the time, Jennifer and Peter were involved because Jack was not around ( don’t remember why). As was state, when Scott found out, Missy left the show immediately.
I remember the thing with her leaving right away, but at the time I remember reading no one knew why, but it was sudden and she was upset with the show or something like that. I also remember the first time she came back it was such a surprise because of the way she left. I guess I never heard at the time about the affair. That is odd that Scott would be ok with this. Maybe they have grown so much that there is trust again and they have a more mature relationship? Who knows.
