4x5 - My Parents Are Aliens

Today Mel is fed up with Lucy's controlling behaviour and decides to move out of their bedroom and into the attic. Sophie sees this as the perfect opportunity to step in as Lucy's new sister. Lucy is incensed, but when Sophie and Wendy abandon her too, she begins to wonder whether she might be in the wrong after all. Josh is desperate to scam Frankie's signed united football shirt from him, and Brian agrees to morph into Mel as part of a cunning plan. But Josh is about to get a taste of his own medicine for once.
