S01E08: 'Whatever Happened To Sarah Jane?' Part Two

Maria desperately tries to talk the young Sarah Jane and Andrea from heading towards the pier, but fails to do so and is taken back by the Graske. She is soon reunited with Sarah Jane on a mysterious, white landscape. The figure with no eyes and a black cloak explains that they can no longer prevent the meteor from hitting earth and creating widespread chaos – something which he feeds upon. After devouring all he needs, he plans to track down The Doctor.

Alan confronts Andrea at her birthday party about his memories, with everyone else now not remembering Maria. Andrea breaks down in her attic and confesses the truth, revealing that the same shady figure in a black cloak gave her the chance to switch her life with Sarah Jane's when she was due to die by falling off the pier.

Now that Alan knows too much, the Graske is quickly dispatched to capture him. However, his skateboarding skills come in handy as he knocks the little alien down with his board and uses the box to bring back his daughter. The Graske is tied up and admits that he is employed only as a slave for this mysterious 'Trickster' (as Alan calls the figure).

The meteor is heading towards earth and the news reveals that there is little hope of it being diverted at such a late stage.

In the attic, Andrea is confronted by Sarah Jane via the mirror. The Doctor's former companion explains that witnessing her school friend's tragic death gave her the resolve to prevent the needless waste of life. This has a profound effect on Andrea, as she hurls the box against the mirror when the Trickster suddenly appears, with the effect being one of reversal. We see the young Andrea fall to her death back in 1964.

With normality now being resumed and everyone returned to Earth, Sarah Jane just about manages to deploy her computer Mr Smith in time to deviate the meteor away from Earth.
