Confused

So Bonnie is pretending to be Adrienne and no one believes Adrienne when she says she's not Bonnie. Did I miss something? Adrienne had a double mastectomy just a bit ago. I'm thinking they'd know Bonnie didn't have one while she was in prison. Has no one thought about the scars? And holy crap! If Lucas gets with Bonnie wouldn't he be able to tell the difference between Bonnie's breasts and Adrienne's? This is beyond stupid!
