This will be my take of brunettachoppa687, TTICSY (phantomofthefandoms) AU, The things I could show you, over on Ao3, please go read their series, it is so much better than mine.
While in the hospital Vlad while originally wanting revenge on Jack Fenton for ruining his life, he soon learns that it's hopeless, so he learns to let go of his anger and move on from his obsession with Maddie. When Vlad finds out that Jack's son is like him, he gives the young halfa a genuine offer to teach and train him, in everything that he has learned.
In my version of this AU, Danny is still 14
Werewolves and vampires don't mix, or that's what Kieran Callisto, a seventeen-year-old vampire, has believed all his life - until he falls for the Alpha's son.
*****
When Kieran meets his new classmate, Mason Kane, he bristles with an unexplainable disdain. Soon it becomes apparent why: Mason is a werewolf. But when a fight turns into a sudden kiss that neither expects, Kieran's feelings for Mason turn to attraction in an instant. None of it makes sense - vampires and werewolves are supposed to be mortal enemies, so why does Kieran find Mason so irresistible? He knows that each kiss is dangerous, each bite is unpredictable...
