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.
 * It would have been in the Sleepers' interest not to be discovered, so it is possible the force field was deactivated while her ears were being pierced so as not to arouse suspicion.


 * 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.
 * It is entirely possible that their discovery by Torchwood brought their plans forward, forcing them to activate in Cardiff.


 * Only the Cardiff cell was activated. It could have been a bluff, but the last sleeper clearly indicates there are others - and they could be anywhere in the world.


 * 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.
 * Jack can't die -- did you really not know that? It's kind of an important part of the show.


 * The Sleeper's blade was still held in place, blocking the bloodflow. When it was pulled out, some blood appeared on Jack's shirt, seeping through, but he'd had time enough to heal quickly afterwards.
 * That makes no sense, blood would appear on the blade as it tore through his blood veins, and he should have been killed by the stab wound, because the blade went through his chest where his heart and lungs are which are vital organs and plus he can't heal that quickly otherwise he would have healed from being stabbed in Exit Wounds.
 * Jack doesn't need that, he simply can't die. He can even survive being blown up from the inside. Perhaps the delay in Exit Wounds was caused due to being drunk.
