Kate Moreau is an ex-girlfriend of Neal Caffrey.
Mozzie told Neal about a rumor he heard that Kate was fencing something and had a location. Neal goes to confront her, successfully finding her. Both of them confess their 'love' for each other, just before Neal gets arrested by Peter.
Neal is Kate's boyfriend. He escapes from jail to look for her once she stops visiting him. Though it is often suggested by both characters and fans alike that she was merely using him.
Mozzie: Kate's relationship with Mozzie is relatively unknown but from suggested that she was romantically linked with Neal, we can assume she was good friends with Mozzie as well seeing as she helped both Neal and Mozzie on several capers as the one seen in Season 2, Episode 11. Mozzie is constantly reminded "by" Neal on how much Kate means to him and yet there are several times through the first two seasons, Mozzie's questions Kate's loyalty to Neal as seen in Season 1 Episode 2 when Mozzie questions Neal about where he hid all of his treasures. Neal told Kate it was San Diego, while he told Mozzie it was in Portland. It was ultimately a test to see who would overturn him first.
Peter Burke: Peter is often frustrated with Neal when it comes to his obsessing over Kate. She is the sole reason that Neal escaped out of a maximum security prison causing his sentence left to go from four months to four more year sentence. Throughout the entire first season and beginning of the second season, Peter constantly has to deal with Neal moping over Kate, her whereabouts and the one thing that could bring her back to him, the Amber Music Box. Peter contacts Kate secretly in order to pass messages or codes to Neal. He believes that Kate is merely using him and that she could possibly be working for Fowler, the man who has control over her.
Robert is Kate's deceased father. She left a paper flower at his grave for Neal.
