Trevor enters Stars in Their Eyes, performing as Marilyn Monroe, much to the disgust of Hamish.

JP discovers an interdimensional time portal in the airing cupboard, which leads to an exact replica of the Pets' house, save for it including a double of JP being the only inhabitant and a highly radioactive uranium mine in the kitchen.
