'Hawaii Five-0': Michelle Borth's return could strain the Catherine-McGarrett relationship
Showrunner Peter Lenkov says Catherine will join the Five-0 team next season, which means that her active duty in the Navy is likely at an end. Lenkov declined in an interview to say how she joins the squad, only that her addition "is very organic" to the show.
On the downside, though, McGarrett and Catherine may not handle that much togetherness all that well. In the five episodes Borth has appeared in previously, Catherine and McGarrett seemed pretty content together -- but that could be partly because they don't see one another very often, since she's usually at sea.
Continuing their relationship is "going to prove to be difficult," Lenkov says. "When she originally joins [the team], they are still dating, but it's going to be difficult -- just like any relationship is with [a co-worker]."
That's next season, though. As for the rest of this season, Lenkov promises a "jaw-dropping" finale, which we'll have more to say about after Monday night's (May 7) Wo Fat-intensive episode. Check back after the 10 p.m. ET airing for more.
