Oh, yeah, couple of things:
Remember how, way back in the beginning, Brandon gleefully told us that "Julia has a temper" and "she is hard to please"? Meanwhile, Julia has comported herself like a lady, though she is being undermined, mocked, and treated like an indentured servant by Brandon's parents. And gaslighted and thrown under the bus by Brandon! She has never raised her voice, never made an unreasonable demand. She's tried to get along and done her best to cope with livestock, reptiles, live crickets, a controlling and demanding set of inlaws, and a spineless and unsupportive fiance. Brandon's set the stage to try to make himself and his repellent parents look good. Uh, Brandon? Epic fail.
And I think Papa Brandon is an abusive monster. Everyone is terrified of him. Betty's hectic grin and non stop chatter is just her way of trying to distract him so he doesn't start breaking the furniture. She's his accomplice and acolyte and thinks if she keeps him to a low simmer no one will get a broken jaw. I'd like to hear from his previous wives. I bet they have some tales to tell.
