The Doctor returns this Easter Saturday (30 March), kicking off the second half of series seven with The Bells of Saint John, a "pulse-racing joyride" which sees him reunited with mystery girl Clara Oswald as they discover what happens when Wi-Fi goes bad...

But what's the Time Lord been up to since he last saw Clara at the end of the Christmas special? Turns out he stopped off to have a go on the swings in a children's playground, and met a little girl who gave him some good advice.

Shame he didn't think to ask her name... 

The Bells of Saint John is on BBC1 at 6:15pm on Saturday 30 March
