Theory:SJA television discontinuity and plot holes/The Gift


 * Just because the Bane gave Luke 'perfect health', why does that make him immune to everything, including things like colds or stomach bugs? Surely his immune system would be the same as an ordinary human's, at least after a few years of living as a human?


 * The Slitheen used improved compression technology in The Lost Boy, so why are the Slitheen now back to using obese people and prone to farting again in the beginning of part 1?


 * The Blathereen claim that they could never kill a human. But why are they still wearing their compression collars like the Slitheen do?
