Did anybody realize that Jace is supposed to be a vampire?!?

Clare explains this on "The Mortal Instruments" website link

"Why didn't Jace become a vampire after Simon bit him?

City of Ashes, p. 192:

"You might remember that when [Simon] was in the form of a rat, and 你 came to fetch him from us, he bit me," 说 Raphael. "In any case, he took some of my blood into his mouth when he did it. 你 know that is how we pass our powers to each other. Through [VAMPIRE] blood."

Jace isn't becoming a vampire because he didn't ingest vampire blood. Simon became a vampire because he did."

no bc Simon bites him and drinks his blood but he does not bite him and let go like a vamp would do if he was turning some 1 in 2 a vamp.

No. In TMI series to become a vampire a person must be bitten, yes, but also taste vampire blood which is why Simon Turns :)

No. Only when the vamp gives their blood to the person, they will become a vamp. In city of 识骨寻踪 simon is in 鼠, 大鼠 form and accidentally bites a vamp, and sucks his blood. A little bit. Not a lot. That's how simon turns into a vamp.

Have is not a vampire because in order to become a vampire 你 have to drinkvampire blood like Simon drank Raphels blood. Also youhe has to be close to death and buried.
