Sasha Alexander - quit after the first 2 seasons of NCIS as agent Caitlyn Todd. She did forgettable parts in forgettable movies for 5 years. Now she’s back in TV on TNT’s “Rizzoli and Isles”. It’s an OK show but nowhere as good as NCIS.
I think Sasha Alexander is married to Sophia Loren’s son and left to start a family.
The way she went out, there is no way for her to return. We don’t watch NCIS anymore anyway - the show seems to be leaning left now.
