Oh la la! There was a lot of heat on "Fae-de to Black."

If there's one thing that Bo and Lauren have going for them, it's that they have spent plenty of time between the sheets since they became a couple. They love each other and have great sex. The problem for their relationship is that it's like Goldilocks and the Three Bears - there's no "just right." The succubus and human relationship is a tenuous one, as shown after their intense love making: Lauren was drained and Bo was not fulfilled to her body's needs.

The situation for Bo became dire after she was injured. She barely had enough energy to stand up, let alone to heal herself. What is a succubus to do? Bo grew up living a "human" life and wants desperately to be in a monogamous relationship, but that goes against her nature. While it's a difficult situation to be in, Bo did the right thing by letting Dyson heal her. In that moment, he was her best option to protect her life, plus she was unaware that he has his love back.

If she would have known the truth, it would have been an entirely different conversation for two reasons:

1. She would have known that it meant something to him beyond just a physical interaction.
2. She would have considered her feelings for Dyson.

As it is now, she's with Lauren, but she also believes there is no possible future for her and him. Regardless of her love for Lauren, when she finds outs the truth about Dyson, she will have to address it.

Bo confirmed that she still had feelings for Dyson after she healed him and said she couldn't be with him any more. It was too "hurtful" for her and for Lauren. While Bo cannot be monogamous, she wants to do right by Lauren. The conversation between Bo and Lauren was painful to watch. The fact that Lauren can't satisfy Bo is excruciating for the doctor and while she understands clinically why, it doesn't make it any easier.

Unless they find a human-to-Fae or Fae-to-human conversion spell, it's an unfortunate obstacle they will have to overcome. With them both agreeing that Dyson is off-limits, who will Bo feed from? Even though Lauren has said she is agreeable to Bo feeding outside their relationship, it is sure to be a source of conflict for the couple whether they want it to be or not.

The case-of-the-week fit well with the relationship troubles that Bo had to address. It allowed her to acknowledge that she needed to be true to herself, just as Dyson realized he needed to let the wolf out more often. Now that Bo has closed the door on Dyson, will he move on with his partner, Tamsin? They were headed off to have some fun and looked likely to get into some trouble. A romance there would certainly add spice to the show. Though, it's unlikely he would commit to her, just like he couldn't commit to Ciara. Though, they could have fun together.

While Dyson and Bo were off solving the case, Kenzi was left alone with a problem of her own. She was brushed off not only by Bo, but also Hale. Now that he is the Ash, he has responsibilities and Kenzi's disregard for his job is unfortunate. She's always been a free spirit, but perhaps it's time for her to grow up a bit. Though, maybe the arm rash is causing her problem? Why didn't she go to Trick? He actually would be better suited to help her any way.

In the end, something horrible happened to Kenzi. Her arm was disintegrating and she was swept away on the street. Hale and Bo certainly will feel guilt over blowing her off now that she has gone missing.

Overall, this was an enjoyable episode. Bo's feeding issue was handled well with Dyson helping heal her and with Lauren understanding her need to feed outside the relationship. Going forward, Bo and Lauren are going to be walking a tightrope. It won't be easy for Lauren to know that Bo is with others, while Bo will have to be careful about who she chooses as a feeding partner. 

My one complaint is that we went another episode without seeing Bo and Lauren just being with each other. It's difficult to see that they have love and not only lust for each other when we see them primarily in the bedroom, making goo-goo eyes at each other, or Lauren talking about weird science stuff. I'd like to see them go out on a date, have a meal, have a drink at the Dal, something ... anything non-sexual together. So far, we haven't seen a well-rounded relationship and if it is primarily a sexual one, Bo going outside it to feed will be a bigger problem than if there is more there.

Will Lauren be able to accept Bo feeding off others? Or will it eat away at her? Was Kenzi's abduction related to her rash? Dyson and Tamsin: Yay or nay?
