What I heard was Thornthwaite starting out by saying that Ma had "it" and knew how to use it or words to that affect. After that her focus switched to Ralph, but that first comment implied that Wa's primary asset (?) was her body or looks, not sure.
Hmmm, I just watched again and caught that. Yeah, ok, it was a bitchy thing to say and took away from the rest of her roast which WAS about Sultan.
