[@AtomicNut] Maybe, it depends on the strain. As a general guide: small injection: thrall/unaffected Medium Injection: Ghoul/unaffected Full Injection: Newblood Of course it all depends on your vampire's specific abilities and strain. So it might well be that your blood is particularly good at ghoulifying people. But if Hank has been ghoulified, then that means he no longer possesses any free will, and is either slaved to your will or is a mindless killing machine.
