So I take it Mayim is more or less out in the Jeopardy! Cinematic Universe? I figured she was a natural fit, being both a sitcom star and former host who they were keeping on the back burner for future projects.
She never got any better.
She was decent....for one of the fill-in non-game-show-host hosts. I think the expectation was that, tag-teaming with Ken, they would both improve. Ken did, by leaps and bounds. She...didn't.
Her refusal to cross a picket line that, while wearing that particular hat, she was fine to cross, just gave them the excuse they needed to let her go.
