Plot hole: When time in Angel Grove is reversed, young Bulk and Skull recognise Kimberley, Billy, and Tommy; but not Rocky, Adam, and Aisha, as they did not live in Angel Grove when they were young - this is even picked up by Aisha. However, Tommy did not live in Angel Grove when he was younger. In Series 1 (Green with Evil) he was described as "the new kid from out of town", and no-one know who he was (which meant he couldn't of lived in Angel Grove, moved away, and moved back). Therefore, Bulk & Skull shouldn't of recognised Tommy.
