Magnum P.I. season 3 episode 15 is coming this weekend on CBS, with the title "Before the Fall." Thomas Magnum (Jay Hernandez) and Juliet Higgins' (Perdita Weeks) relationship is something that might be addressed here -- whether they're just friends or something more could evolve later on.

In the promo of Magnum P.I. season 3 episode 15, the titular character made it clear that he and Higgins are "just friends." But, despite that, there have been clues that their relationship could turn into something more. Perhaps, there are several factors why he couldn't truly admit his feelings towards her.

At the moment, Higgins is in a relationship with Dr. Ethan Shah (Jay Ali). While Magnum didn't show any signs of jealousy, he distances himself from the two. He used to have his partner's attention most of the time, but everything has changed when she started dating her boyfriend.

As the crime-action drama progresses, many were hoping that Higgins and Magnum will be romantically involved at some point. The latter was also willing to marry Weeks' character so just she could stay in the country. However, that didn't happen as she found another way to stay.

In Magnum P.I. season 3 episode 15, things between them may further change as Higgins makes a huge step when it comes to her relationship with Ethan. She decided that now is the right time to tell him about her past. More stories might be opened here and some revelation could further make them stronger.

But then, Higgins revealing her past to Ethan may affect Magnum in some ways. He knows that he can't just ask personal questions to her, given that he claims that they were just friends. It looks like the possible romance between them will become more complicated this time.

As for what else is coming in Magnum P.I. season 3 episode 15, Magnum will have an unexpected visitor. His Uncle Bernardo (Steven Michael Quezada) suddenly shows up and revealed some shocking secrets about the titular character's mother.

Meanwhile, TC (Stephen Hill) comes to Higgins and asked for help as he believes that he may have witnessed a possible murder from his helicopter. While investigating this, TC will also give Shammy (Christopher Thornton) an opportunity to become a pilot.

Magnum P.I. season 3 episode 15 airs on Friday, April 30, on CBS. The already-released episodes are available on the network's official website, while the series can also be streamed on YouTube TV, Fubo TV, Tubi TV, and DirecTV.
