Blade: You better wake up. The world you live in is just a sugar coated topping. There is another world beneath it. The real world. And if you want to survive it, you better learn to pull the trigger.
When Frost has the head pure-blood vampire on the beach, after he pulls out his first vampire tooth you see blood all over his mouth, but when it shows the closeup of him pulling out the other tooth, there is no blood.
In the Marvel Comic series where the characters originate from, Deacon Frost was actually an elder man, and an alchemist who dabbled in vampirism and - via one of his experiments - turned himself into a unique vampire who could create doppelgangers of his victims.
