This week the pop-up parlour is saving more customers from their tattoo traumas. Sketch is visited by John, an extra-terrestrial enthusiast whose tattoo is on another planet, Jay is working on Alec, who made a big mistake with a tiny inking, and Alice is helping out Jenny, whose eye-popping tattoo comes with an equally shocking story. Plus there's double trouble when Jay and Sketch team up to help David, whose cheeky tribute to his ex and her mum struck a bum note.
