When you think of crime shows, chances are romance isn’t the first thing that comes to mind. But that doesn’t mean they can’t have some of the best relationships on TV! What better way to get ready for Valentine’s Day than to find love where you least expect it… in the middle of crime?

Now, because of the nature of the genre, episodes don’t focus as much on the personal lives of police officers. But even a few scenes or a big moment can make you remember or love an episode because of a development that’s made for a favorite couple. In some cases, it’s more obvious, like a couple finally getting together (like in NCIS: Los Angles and Castle) or sharing a first kiss (The Rookie and, in a twist, Bones). But sometimes it’s the little things, like what could have been (NCIS).

Below, we take a look at these and many more of the most romantic crime series episodes (in alphabetical order by series).

What better way for the police family drama to finally bring Jamie (Will Estes) and Eddie (Vanessa Ray) together than with her saving his life on the job, followed by an emotional hug on the street, and then a surprise for everyone (the Reagans, fans) at the end of Sunday dinner? Jamie was late — but he wasn’t alone: Not only did he bring Eddie along, but they announced they were engaged! They completely skipped the dating phase of their relationship.
