Keeping your business and pleasure separate is really hard to do, but this is the thing which Thomas Magnum is going to learn. Magnum P.I kicks of his fourth season on Friday, and the Hawaii-based private investigator finds himself in a bit of a pickle when he bumps into Detective Lia Kaleon (played by new series regular Chantal Thuy) at the office. In the beginning things were well between Magnum and Kaleo, as the two banter back and forth was about his reputation for being “thrifty” that made things heated up in no time when Magnum asked detective Katsumoto, who’s partnered up with Kaleo, to look into a potential missing woman. With that coast clear, Kaleo smoothly slips Magnum’s missing watch out of her purse and into his hand.

“Where was it?” a surprised Magnum asks, prompting her to reveal, “At my place.”

“Well, obviously. But I checked everywhere before I left, I couldn’t find it,” he says. 

“There’s a little Bermuda Triangle couch cushion situation that.,” Kaleo begins to tease, before catching Katsumoto out of the corner of her eye. With a blink of an eye, she flips on the professional switch, giving Magnum a hint that their time to flirt is over. “You may want to check hospitals. Maybe she was in an accident.” Watch the rest of the season 4 premiere sneak peek to see what happens next.
