Although we know her dad has passed on, if they did a flashback he could be involved.

I wouldn't mind seeing Abby's mom or other relatives. She is the only one on the ream who hasn't had a family memeber visit or do flashbacks with so I think it really is her time for it

^ I agree. I think it would be fun and interesting seeing her with her family.

Maybe there's a reason why Abby isn't involved with her parent/s. We don't really know much about her past. Maybe they were boozers or abusers. And we DiD meet McGee's sister, and she was kind of bitchy. We haven't met anybody from Abby's family
