That would make sense. It would be cruel if a parent just flat out told her daughter she hated her.

Plus Sammy was telling Amy that mom hated her. Implying that Amy didn't already know. It sounds awful, but I'm kinda glad about that. I already headcanoned that Sammy's mom favored her while their dad favored Amy.
