On May 6, 2022, the Season 4 finale for Magnum P.I. aired. The finale teased a burgeoning will-they, won't-they romance between Juliet Higgins (Perdita Weeks) and Thomas Magnum, until Higgins sees Magnum's ex, Lia, emerge from his bedroom. Once again tabling her feelings, Higgins and Magnum work to help Gordon recover his ex-wife Beth from being kidnapped.

After rescuing Beth and working to catch the blackmailer behind the kidnapping, Suzy (Betsy Phillips) goes into labor with Rick's (Zachary Knighton) baby and delivers a healthy little girl. During their time at the hospital, Higgins needs a moment to escape and Magnum follows her, asking what's wrong. She confesses she went to his home to state her feelings for him but retreated upon seeing Lia.

Luckily, Magnum explains that Lia was just in need of a place to crash after partying the night before and says that he slept on the couch. Higgins and Magnum are finally able to mutually confess their feelings for one another and they share a kiss as the screen fades to black!
