In my story, Finn is a female and a heretic. She was married to Alex who died along with Henrik at the hands of werewolves. When Mikael stabbed Finn what no one knew was that Finn was pregnant and the babies sensed danger. They did magic to protect themselves thereby freezing the pregnancy. Although Finn still showed symptoms of being pregnant as a vampire. She puked blood, feel hungry, magic going haywire and losing control over bloodlust. When Finn died at the hands of Alaric Saltzman she went to the other side where Uncle Aaron told her the truth about her pregnancy. The babies resurrected Finn which unfreeze the pregnancy
