Detective Kevin Ryan is a member of Kate Beckett's team and partners with Detective Javier Esposito. His colleagues at the precinct frequently poke fun of him, especially because of his nickname: Honeymilk.
He is in a happy relationship with a young woman named Jenny, who, as Esposito says, has him "whipped."
To Esposito's horror, he reveals that he got the couch in his apartment on which he and Esposito frequently sit to play video games, from the corner of 54th and Lexington Avenue, where someone had abandoned it.
Kevin Ryan is played by Seamus Dever.
