Karen Gillan is a former Doctor Who television show sidekick companion and currently playing a comic book villain named Nebula in The Guardians of the Galaxy. Karen Gillan is standing side by side with soon-to-be-former Doctor Who #11 Matt Smith. Both Karen Gillan and Matt Smith is standing in front of Marty McFly and Doctor Brown's time travel machine designed as a Delorean automobile. Sadly, The flux capacitor is out of order again. Thankfully, Doctor Who might have a spare The flux capacitor lying around somewhere in the Tardis. If only he knew where he last left it. If only he had a clue.
