Victor Webster—the genetically-blessed alum ofMelrose Place 2.0, Charmed, and Mutant X—is joining the ABC hit as Beckett’s (Stana Katic) new love interest. 

Webster’s character, Josh Davidson, first appears in this season’s fourth episode when he drops by the precinct to visit Beckett. Unlike Bec’s last two boyfriends, played by Bailey Chase and Michael Trucco, Webster’s Josh is not in law enforcement—a fact that’s not lost on Castle.

“There’s an element of mystery to him,” explains exec producer Andrew Marlowe. “He’s more of a motorcycle guy…A person that is going to intrigue Castle, because he’s going to see a different side of Beckett.”

Webster will appear on a recurring basis throughout the season.

In other Castle news, Marlowe confirms that the show’s youngest star, Molly Quinn, is also getting a love interest in the form of Secret Life of the American Teenager‘s Ken Baumann.

“This is her first serious boyfriend,” notes Marlowe. “This is the first time Castle has had to deal with his daughter being in a relationship.”

Castle‘s third season premieres Sept. 20.
