Lucy is wearing her leg cast, which she did not have on in the previous episode indicating that these episodes were aired out of filming order.
When Lucy is undercover as Dirty Gertie, she blacks out her teeth and sports a mole, but still has on her usual glamorous eye make-up.
Rocky and Benny somehow do not recognize that Lucy Carter is not the same Gertie they formerly encountered outside (and inside) the Pink Rooster Cafe.
