Yet another missed opportunity on Cassandra Clare’s part. I know, I normally moan and groan about her info dumps, but this would have been the perfect time for her to actually give us some exposition for once. With different vampire mythologies, the difference between a species blood, or even blood type could have a lot of different consequences on the vampire who is feeding. This trope is actually used in shows such as ‘The Vampire Diaries’ and ‘Angel’. When the vampire feeds on animal blood, the vampire is weaker in both strength, and extra sensory abilities.
Yeah, Clare didn’t have use this trope, that’s perfectly fine with. However, you can’t just lampshade it with ‘Blood is blood’. In my opinion, you have to explain why any type of blood has the same effect. Also, I want to, again, point out how Jace knows literally nothing about vampires. It was pretty much shown back when they were first discussing Simon being turned. Yet, he’s just so sure that any blood will do. Again, this would be a great time for Raphael, you know the fifty year old freaking vampire, to actually chip in here.
*Melissa’s comment : So this is just bothering with Gigi pointing it out. Even Smeyer made up a reason for her sparkle-pires, I mean “vampires” to survive best on human blood. Even if she never actually proved it to be true in her books. Animal blood, supposedly made the sparkle-pire weaker than human blood, and even the type of animal was supposed to make a change. Clare, when goddamn fucking Smeyer, fucking made a reason for using different blood, you have no goddamn fucking excuse at all. Fuck off CC. Just fuck off forever.*
