Stephen (Attack of the Space Leeches!)

Stephen was a young boy with a cold when Space Leeches crashed a ship near Primrose Hill, London in April 2010. The TARDIS materialised around him and the Eleventh Doctor manufactured a highly infectious virus from Stephen’s cold virus that weakened the space leeches' hold over people. The Doctor assured Stephen he would take them to a safe place. (COMIC: Attack of the Space Leeches)
