What ever happened to Freddies dad?

I was wondering the same thing. and sams dad and carly's mom.

he died

I'm sure he got fed up with his psychotic wife and left her.

they got divorced.

Actually, nobody knows. I guess it's the same thing with Spencer's and Carly's mum. I assume they are not important for the story line.

Wate, I thought Carly's mum was with their dad? ^_^
