Theory:Torchwood television discontinuity and plot holes/Sleeper


 * If the Sleepers cannot be pierced, then how does Beth have ear-rings?
 * She probably got them from the same shop that serves Claire Bennet'
 * (if you look at 24:03, when Beth is about to be frozen, you can see that they are proper ear rings, not clip-ons).
 * Possibly she got them before her protective force field was activated as a simple part of her disguise, false memories and all.


 * Why are all the sleepers in Cardiff? Surely they would spread themselves out in order to make the invasion more successful?
 * The Sleepers came to Earth through the Rift, they may have been attempting to secure the Rift and open it with the nuclear missiles in order to summon the invasion force. As not knowing how many they truly are, they could be used for another story Arc.


 * The sleeper agent stabs Jack right through his chest yet he doesn't die, no blood leaks out of his wounds and no blood has stained the Sleeper's blade
