10 Best Doctor Who Characters In One Scene Only

Since we're bending the rules with older/younger versions of characters, it would be an absolute crime to exclude the senior Billy Shipton from Blink.

Blink has been praised to death ever since it aired (and rightfully so), but a moment that isn't talked about enough is the scene in which old Billy enjoys a final, heartfelt conversation with Sally Sparrow, before peacefully passing away.

Having watched Billy's charming younger self flirt with Sally literally two minutes before, we immediately feel sympathetic towards this older version, who has lived a long, complicated life after being zapped back in time by the Weeping Angels.

The stark contrast between the fast-talking, energetic, twenty-something Billy, and this weary, ill, and pensive one is utterly devastating, and it's a real kick in the stomach when he rests his wrinkled hand against Sally's, tearfully wondering aloud where all the time has gone, and how he came to be this way.

In a single moment, writer Steven Moffat and director Hettie MacDonald capture the true horror of the Weeping Angels, with actor Louis Mahoney only elevating their work with his incredibly moving performance.

A few moments later, and Billy is gone - leaving behind a scene that has more emotional texture than most entire episodes do. To everyone involved: bravo.
