Elliott Gould – Exiting
Elliott Gould returned as Legal Siegal in season four, but his character was killed off.
Lorna approaches Mickey and Maggie in season 4, episode six and says, “Legal had a heart attack. He was on the bus, and we were talking. I thought everything was fine. He’s gone, Mickey… I talked to his son and they’re gonna try to do the funeral in the next couple of days.”
Yaya DaCosta – Exiting
Yaya DaCosta did not return as Andrea Freeman in season four, and her character is also not featured in “Resurrection Walk,” the book taking the focus in season five.
It seems unlikely that she’ll return as that time, unless she is written in specifically.
