In the movie Blood & Chocolate from 2007, the protagonist's aunt, Astrid has a son, who she mourns deeply, so I assume she's his biological mother.
But, Gabriel, the leader of the pack, is also referring to him as his son and also mourns him. Yet, he only has been with Astrid for 7 years as of the time of the movie. But said cousin is well over 7 years of age.
So who are his biological parents? Did Gabriel adopt him, or Astrid? Or neither?
