"McGarrett talks about Catherine and the status of their relationship," said executive producer Peter Lenkov, according TV Guide. "I know people have been asking, 'Where's Catherine? What's happening with Catherine?' So we're going to answer that."

Although McGarrett recently met a new female acquaintance, he is reportedly still caught up with his old flame.

"He's taking it hard," Lenkov explained to TV Guide. "There's still this mourning period, because even though they didn't break up... she chose to stay behind in Afghanistan, and that actually hurts. So it's definitely on his mind."
