"You don't mean I have to drink blood now do you"? Warren asked carefully.
"Why? You said blood doesn't bother you"? Karen raised her eyebrow with a tiny smirk.
"Neither does a truck! Doesn't mean I go ahead and eat it"! Warren cringed.
"Well, you gotta drink blood". Karolyn shrugged. "Also, Human blood. Any other blood won't do"
"What"?! Warren shouted! "I can't hurt another human being. I… Let's go look for a blood bank"! Warren suggested.
"Nope" Karolyn said flatly.
"Why not"?! Warren shrieked.
"Blood banks have frozen blood, you need the warm kind… to take effect". She smirked.
"But I…" He hesitated. "I can't kill a human".
"You don't have to kill anyone. Just a sip is enough". She shrugged.
"What about vampire venom then? Doesn't half kill cause them to turn into vampires".
