Doctor Who: The Age of Steel

The Doctor, Rose, Mickey and the rebels begin a three-pronged attack to bring down Cybrus and the Cybermen, but not without some sacrifices. The Doctor figures out that Cybermen retain traces of their personalities despite being brainwashed and manages to reconnect all of their emotion chips, thus making them recall all the horrible things they've done, effectively torturing them all to death until they explode. Once their plan is complete, The Doctor and Rose prepare to return in the TARDIS to their universe without Mickey, who has decided to lead the rebellion in this universe.
