Blood theory
They keep on making a big deal about Bo being Trick's blood to.
Anyone else thinking she is going to inherit Trick's Blood King abilities?
We already know that if Bo's blood comes into contact with an open wound, it thralls the person (it happened to Ryan Lambert after she sex-healed with him). Saskia/Aife thralled her male harem in Season 1.
In Flesh and Blood (2x22), to defeat the Garuda everyone (except Lauren and Kenzi because they were human) were bound to Bo with her blood.
In Origin (4x12), Sister Epona, the leader of the Women of the Horses, told Bo that her blood would destroy her father, the Pyrippus:
SISTER EPONA: Your blood will destroy him. He must be protected.
BO: Protected from who?
SISTER EPONA: Succubus. You.
And in Dark Horse (4x13), Trick told Bo:
TRICK: Aife has my Light blood. The blood of a mage. Blood that drains life for nourishment or self survival. But the blood of your father...whoever he may be...allows you to draw life from many victims...and more importantly, to transfer that life force to someone other than yourself. You've inherited the abilities of both your mother and your father.

The subject of Bo's blood power has been building for the last four seasons.
Yep, they really have been building on it ever since they told us about the blood king and what he could do, and they've basically been jamming it down our necks these last few episodes that she has tricks blood in her veins.. and then.. they did.. NOTHING with it?!
It was basically a throwaway line that was nothing more then "oh, I'm not just created by someone evil, I'm also related to someone good". WHAT?! that was it? We knew that already, and the fact that she still didn't seem to REALLY get that until then, just baffles me?!
Boohoo, my daddy is evil, I must be evil too? how many times have we heard that stupid spiel.
So the big reveal, is that she finally understands that she has good people in her familytree too. Wow. I'm so shocked and amazed. No. Just no.
I'm deeply disappointed that It wasn't something cool, like that she could use her blood to write and make her wish come true like Trick could (or something else significant) worst non-payoff ever!
And also this whole nature vs. Nurture thing. When are people gonna get that we decide for ourselves what we do and who we are. It wouldn't make a lick of difference if all her relatives where evil. She can still decide to be good, she can still be strong, and fight for what she believes in. Jesus Christ.
