Another CBS series regular is saying goodbye.

With fans of The Good Wife still reeling over the loss of Josh Charles, sources now confirm to TV Line that Michelle Borth will exit Hawaii Five-0 following the Season 4 finale.

The actress has portrayed Catherine 'Cat' Rollins since Season 1 and was promoted to full-time status for Season 3.

She will make her final appearance as a well-tanned team member some time this spring, with producer Peter M. Lenkov possibly hinting that it will take place on the penultimate episode of Hawaii Five-0 Season 4.

He recently told TV Line that installment will be a “dramatic” one that features "some flashbacks to [Catherine's] stint in the military."
