1) Noah, because he's invisible.
2)
Cyrus, because he's wearing black and that tight-lipped frown is
probably hiding fangs
3)
Cedric has that "hiding fangs" frown too.
4)
Elena, because she's got that telltale
vampiric widow's peak. She probably has a transylvanian accent too,
she just dresses like she shops at the Gap.
5)
Ian, because he's too perfectly good looking
to be really human
6)
Sierra looks like she doesn't get enough sun.
7)
Iskendar, maybe. It might explain how he managed to ... never mind!
But he should take fashion lessons from Ian.
8)
Suri, because the only picture we have of her is at night.
... Um, it's late, and I'm running out of blood. >:-)
