Son (The Bounty Hunter)

From Tardis Wiki, the free Doctor Who reference

A woman's son lived circa 2050.

He and his sister were trapped on a ferris wheel, which started moving rapidly as their terrified mother watched. A Department force led by Inspector Drake arrived on the scene. He addressed a crowd of shocked people, alerting them that a bomb had been connected to the speed clutch in the control centre and if they tried to stop or even slow the wheel the bomb would detonate. K9 Mark 2 and Starkey destroyed the bomb, slowing the wheel down and saving the boy and his sister. (TV: The Bounty Hunter)
