Just a few drops of blood would be enough to quench her new thirst. Instead of Eli just getting rid of the bodies afterward, he should hand them over to her so she could have a meal. She packed bags of blood and saved them for when she needed to drink but had no food source insight.
Helen only drank the blood of vampires and occasionally demons because the demons mostly stayed in the underworld. She had no plans to go down there just for food. Because Helen worked for the hunters, she knew which vampires had done something bad so she would drink their blood after killing them.
She tried human blood a few times but it always tasted foul. It took her a long time to realize the blood she needed did not come from humans. The first time she tasted vampire blood it was like she tasted the sweetest thing in the world. It was unexpected vampire blood was her food source because she never heard of anyone drinking their blood. It was always the other way around.
