Det. Lovato
Obviously, we're supposed to like Jamie Lovato - and I do, at first glance. She could be Aiden and Jess' big sister, with all their similarities in looks and attitude. Just as feisty but more grounded than Aiden, and just as friendly but less angelic (to coin a phrase) than Jess the ever-good-humoured.
My only gripe, and it's a small one, is that not one of the cops I have ever known would turn up for a new assignment in anything but professional attire, be it uniform or court suit! I get that she was supposed to appear as if she was on the other side of the law, at first, but a cop would never be told, "Okay, your cover is blown. Go straight to your new precinct and don't even stop to change out of your druggie duds." Heck no. She'd sit cooling her heels in her home office for a week while they figured out if her residence was safe, how to relocate and reassign her and debriefed her on every contact she ever made.
Other than that, I wish her (and Ms. Martinez) well. And Flack. I think she's already got his number, in more ways than one.
