 * If River is Amy and Rory's daughter, why wasn't she erased along with Rory when he died in Cold Blood?
 * Simple. When Amy's parents were erased from time, Amy continued to exist. Therefore, when Rory was erased from time, River continued to exist.

perhaps they stole the ships?
 * Why would the Cybermen have safety signs on their ship? There's clearly a "Fire Escape" sign and another denoting the contents of the tanks in the background while the Cyber Leader calls out intruders. TehDash 05:45, June 7, 2011 (UTC)
