Castle is upset to learn that Alexis has a video blog where she’s sharing personal info with the entire world. It’s nothing as salacious as the stuff Beau Randolph produces. We first the man behind the tawdry “College Girls Gone Crazy” video empire in Season 4’s “Head Case.” The guy is still a purveyor of porn, but he doesn’t seem as carefree as he once was. In fact, he looks downright conflicted right up until the moment he’s strangled to death with a bra inside a club bathroom.

Esposito takes an immediate interest in Beau’s bodyguard, a beautiful lady named Scarlet Jones. She says a soft core porn star named Tiffany Shaw is likely behind the murder of her boss. The woman was obsessed. Beau’s cameraman/producer, Troy Strickland, agrees that Tiffany is a good suspect, but he didn’t see her in the club. He also says Beau had no family of his own. It’s as if he was always looking for one though. As for the case, Castle and Beckett see security video of Scarlet Jones breaking into Beau’s safe. Espo is bummed.

Scarlet says she broke into Beau’s office to steal a sex tape that her friend made. She took the security job to make sure the video never got released. Scarlet also broke the nose of a guy who got physical with Beau awhile back. Esposito supervises her work with a sketch artist. When they are done, he asks her out on a date. As for the guy in Scarlet’s sketch, his name is Seth. He was trying to get Beau to partner with him in a new video series featuring male stars. He calls it “College Guys Gone Nuts.” Catchy.
