Michelle Borth, the actress who plays Lieutenant Catherine ‘Cath’ Rollins on the CBS hit drama “Hawaii Five-0,” will not be returning to the show next season, according to TVline.

Borth, who has been on the show since the first season, has played McGarrett’s (Alex O’Loughlin) love interest. She will make her final appearance at the end of this season, the show's fourth.

In a recent interview with TVLine, executive producer Peter M. Lenkov revealed that the second-to-last episode will be a “big, dramatic” one for the couple, with “some flashbacks to [Catherine’s] stint in the military.”

No word yet on the reason for Borth’s departure, though a tweet from the actress on March 17 might suggest that she wasn’t thrilled with the gig.

It's time to MOVE ON from all the negativity, so going forward I'll no longer discuss anything 5-0 related what so ever. Onward and upward! — Michelle Borth (@michelleborth) March 18, 2014

Borth, who became very active on Twitter when she joined the show, told the Honolulu Star Advertiser last April that she wanted to embrace “all the love” that fans had to give on Twitter.

Apparently, she’s no longer feeling the aloha.

“Hawaii Five-0” airs Fridays at 9 p.m. on CBS.
