The Importance of Dad in Loss

I wonder how much is Oscar hyper fixating on the moments he had with his dad and that's what we're seeing as opposed to how involved mom was because of how in touch she is with him. I think dad was just yeah a little better at that particular thing for him all right and go ahead then something that I also want to touch on with this is that sometimes when people go through a loss particularly one that they are experiencing trauma on and are hyper focused on trying to resolve the traumatic part of it  can start to distort the relationship or the importance of it.
