Bloody Vampires, have to mess everything up!

What if Carlisle wasn't married to Esme? Or interested in women in general? And a young man, hardly more than a boy, just stumbles into his doctor's office. Helios has a lot to do, even without a relationship. A violent father, a little brother without mother, school. On top of everything a bloody vampire starts to give him some real bad headache. Or is it a heartache?
