Theory:Torchwood television discontinuity and plot holes/Cyberwoman


 * Why did Tosh not know what the device, to open the doors, was when she used it to extract information from books in TW: Everything Changes?
 * It is presumably intended to be a different device which simply looks similar.
 * Given that she should never have taken it out of the Hub, it's likely she would feign ignorance.

 * Dr Tanizaki's conversion makes no sense, parts of the Cyberman helmet were placed under his skin, if he were to be upgraded, the Cyber-Skin would be placed over his skin, like Lisa.
 * The conversion was a failure, and it isn't certain that the conversion unit was attempting to turn Tanizaki into a compromise cyberman/human form like Lisa's.


 * How is it, that when Jack gets shocked twice by Lisa, he dies, yet he was able to survive many other things, like stet radiation which would usually kill people. so how could he survive that, but not survive the electricity?
 * His immortality presumably exists at a cellular level, and so the stet radiation (which would destroy the cells) doesn't disable him, as the cells are regrowing as they are destroyed. This process causes him obvious pain. The electrocution, however, works on a higher level and damages body functions.


 * When Cyberwoman shoots Jack's gun, wouldn't it explode? Like in Doomsday a single shot was enough to blow up a car or Made of Steel when their guns blew up the weapons.
 * Lisa is only partially converted, so her wrist-blaster could be weaker.
