After taking a clown's ball to the face Luke keeps hearing the phrase "Beware of something nasty pretending to be something nice" and instantly assumes it refers to Galvin. After some prompting from a medium (played by Mrs Doyle off 'Father Ted') and the villain Thrip from Ep 1, the dim mouth breather Luke decides Galvin is his enemy and has to die.
Luke is so pitifully drain slime stupid that Galvin decides to tell him that the phrase refers to Luke's dad who went over to the dark side. Meanwhile Mina is set up as a baddie for season 2. Please no. This was utterly utterly dreadful.
