Fanon:Heimdall Horner

Heimdall Horner was the father of Blue Horner and Jack White, although the latter's true parentage is kept a secret and Jack's official father is Layton White.

Weeks 01-09
After moving into town with his son Blue, Heimdall is seduced by Talia White. They have an affair, and Heimdall unknowingly gets Talia pregnant. Talia keeps the pregnancy and gives birth to a son, Jack, although Heimdall is not told and everyone is led to believe that Jack is actually Layton's son. Some time after Jack is born, Talia visits Heimdall and breaks it off with him, parting ways with one final kiss. The next day, Heimdall is found dead in his home, the cause unknown.
