Iris: I am dating Eddie whether you like it or not.
Joe: Eddie's my partner.
Iris: I know.
Joe: But you don't. You're not a cop. You don't know what having a partner means. Wherever I go, he goes, and where I go isn't always safe, Iris. I need to be 100% focused. Now, there's a part of me who isn't focused, who doesn't see Eddie as my partner but as your boyfriend. So if he gets hurt, or worse, and I'm there? How am I gonna look at you? How are you gonna look at me? Now I'm not mad at you, but that's why this is so hard for me. Do you understand?
