One of the things I value most about Moonlight is that almost no one -- not Mick, not Josef, not Coraline, not Beth -- not even lesser characters like Josh or Carl or Guillermo or even Sam the hacker -- was presented as a simple, one-dimensional character. They had positive and negative aspects. They all acted selflessly at times and selfishly at others. They had little unexpected quirks that made us pay attention. That's why Moonlight caught us up in its world--because the inhabitants of that world felt real to us.
This little essay reflects my own views, and I understand that not everyone shares my opinion. I respect everyone's right to their opinion, but I think it's important to think about.
I believe that it's a disservice to the characters of Coraline and Beth to interpret either of them one-dimensionally, either as purely "good and true" or purely "selfish and manipulative" (and you could paint either character with either label, depending on how you choose to interpret what you saw on the show).
Both women were damaged souls whose strength of character allowed them to survive horrific experiences without being devastated by them. Both were conflicted regarding Mick. Both drew his interest and his passion, in different ways, and both returned it--again, in different ways. They sacrificed greatly for his sake, and yet they did things to hurt him. They both laid their hearts on the line for him, and they both did things he would consider to be betrayals.
Beth obviously felt a connection to Mick immediately upon meeting him. Have you ever met someone and felt that instant, deep connection? I have... and that can sometimes lead you to behave in a way that isn't kind to others (as Beth truly
was unkind to Josh). Yes, Beth was definitely a danger junkie, but I don't think she would have reacted the same way to any other dashing stranger who swept in and caught her eye... she reacted to Mick because of the bond they shared. Mick said it himself at the end of Fever: "Or maybe we've always been connected." Did she blow hot and cold at Mick? You bet she did. Her heart kept leading her one way, and her head the other. Josh was always the logical choice; but logic doesn't work against that connection.
No passion between Mick and Beth? Did you see that kiss on the roof?!

Yes, they were at the very beginning, and their relationship couldn't possibly be like Mick's and Coraline's. For one thing, Mick had to overcome 20 years of seeing her as a little girl growing up. And partly because of that, he had a tendency to speak down to her--but she was already teaching him that she was worthy of his respect. Their attraction and growing passion burned brightly through the guilt and the awkwardness, and they were figuring it out.
Coraline was obviously captivated by Mick the first time she saw him, and she allowed him to batter down her defenses--she reveled in the wildness she brought out in him. As for whether or not she loved him? Look at it this way: she dared to marry him, against the wishes of her powerful family. On their wedding night, when he said "I'll love you forever," she asked him again, and he reaffirmed it. She took it literally, unfortunately, but she did ask. Was turning him without explaining things a horrible mistake? Sure, and Coraline would be the first one to tell you so. But think about what she did from a vampire's point of view (a vamp who
loved being a vamp). She loved him enough to grant him eternity as her husband, including a place in her aristocratic and immensely powerful family. And after he rescued Beth and left her for dead, she loved him enough to forgive him for
burning her alive (well, undead). Just think about
that for a second. We know from show canon that vampires feel pain when they're injured, so just imagine the hideous agony she suffered at his hands. Could you forgive someone for doing that to you if you didn't love him? I don't think so. Coraline loved Mick enough to steal the cure from her family, use it herself--giving up all of the powers she herself held so dear--and try to lure him back to her. Was she manipulative? You bet your boots she was. Did she mess with his head by simulating the very fire that he "killed" her with? Yep. But after what he put her through, I think she felt he had it coming. Heck, I'm a MickBeth shipper, and I think he had it coming. The very least he could've done was to kill her cleanly with a blade, rather than leaving her to burn.
I don't want to get too far ahead, but I also believe that Coraline gave Mick the mortal cure, saved Mick from her brother, and put herself in Lance's hands, allowing herself to be taken to who knows what hideous fate, out of love for Mick. Just as Beth fed Mick her blood in the desert in order to save his life, Coraline gave herself up in order to save his life.
Coraline and Beth are almost like counterparts, and they both loved him in their own ways, just as he loved both of them.
Oh, and one more thing. Don't forget that this is a TV show.
I tend to forget that myself when I get all impassioned... and YES, isn't it a tribute to the wonderfulness of Moonlight that it affects us all this way?! But it's not worth making enemies over. I'm giving up on saying that it's not worth losing sleep over, because I've been losing sleep over it since I fell in love with it and started writing when I should be sleeping...but we're all here because we love the show so much. We need to remember to be kind to each other and try not to give and/or take offense. It's all about respect and kindness.
