I agree that Aquirre & Jack's ma knew early on. I think as Alma, Jr. got older that she knew. We know when Alma found out, although she didn't know what it all meant. She was angry confused, & devestated. I don't think Loreen knew for sure until the phone call from Ennis, but I sometimes wonder about the question..."wonder why husbands never want to dance w/ their wives, Jack"?
