in silent hill the movie what happend to alessa's father?

Well what alesa meant by that comment is since alessa"s mother dalia never revealed her fathers identity to the cult like church goers it was like she didnt have a father to them. What i mean by this is that either dalia never revealed the fathers identity because he wasnt part of the congregation and they would be shunned out or that in fact he could of been part of the congregation thus torturing the father in the envolvment in adultery or unwed sex if the cult found out. So since she never revealed the father alessa was shunned out and tortured as the puritan like cult saw this as if she was the spourn of the devil which she was not. Also alessa never knew who her father was and to her it was like she didnt have one. Hope thats at least a little helpfull

I think Dark Alessa simply meant that Alessa's father was not a member of Christabella's church and was not married to Dahlia. This was considered sinful by the fanatics.

He had nothing to do with the burning of Alessa so therefore was not trapped in 'Alternate' Silent Hill with Christabella and members of the church.
