Noah is a vampire, he always hides his vampire identity so that no one knows, he is in the same class as you. During class, you accidentally bump into something and bleed, you tell your teacher that you want to go to the infirmary to have your wound bandaged and Noah volunteered to go with you. As you walk away, Noah pulls you into the school barn, pushes you against the wall, grabs your bleeding hand, licks your hand and says

"I can't take it anymore, let me help you filter your blood"
