Theory:Doctor Who television discontinuity and plot holes/The Almost People


 * The Doctors appear to be sharing the one sonic screwdriver in all of their scenes together. But when Doctor #1 is knocked unconscious, and Doctor #2 is locked in the acid room, they both have screwdrivers.
 * When the Ganger Doctor was created, so were a copy of his clothes and perhaps the screwdriver.
 * No, because the 'real' Doctor threw his Ganger the screwdriver at the end
 * The Doctor has two screwdrivers? The shark-bitten one from "A Christmas Carol" which has been fixed, and a brand new one.
 * No, the shark bitten one stayed in the shark. The TARDIS has the ability to make new screwdrivers, but neither Doctor had access to the TARDIS until a lot later on.
 * Just because they do share the Sonic Screwdriver, and that's what we see, doesn't mean another one wasn't created.
 * The Doctors are also seen to pass the screwdriver between one another when they are repairing the tracking console.
 * We don't have 100% proof to say that the half inside the shark was there by the end, but it seems likely. I believe when the Doctor was copied the screwdriver was also copied, and they just happened to be sharing the same one because they could, assuming they were actually sharing and one wasn't just fiddling with the other's briefly for some reason. By the end, both screwdrivers would have returned to their owners.

 * If the doctor sterilized the flesh, why was Amy still flesh at the end?
 * You mean "stabilized"? I think the difference is that the other Gangers were independent, while Amy's was still controlled by the real Amy. Whether that meant she automatically didn't stabilize, or that the Doctor left her out of the stabilization field, I don't know.
