Charlie (The Gunpowder Plot)

Charlie was an urchin living in London and a friend to Barnaby. In 1605, he discovered a Rutan ship with ornate doomsday weapons inside beneath Parliament, which he thought were treasures he could use to help his sick sister Annie. He snuck his way past Sontaran troops with his slingshot and marbles. The ship had trapped Charlie in the organic matter, but Rory Williams cut him free. Thinking he and Amy were disguised Rutans, Charlie escaped along with the weapon, leaving his slingshot behind.

When Parliament was taken into orbit with Charlie inside, Field Major Kaarsh took him and Amy for questioning, Charlie dropping the doomsday weapon. Rory saved them by firing a slingshot into the Sontaran guard's probic vent. (VG: The Gunpowder Plot)
