Not only are we seeing the Doctor return to The Sarah Jane Adventures but we also get the return of former Doctor Who companion Jo Grant (Katy Manning).
As a treat, Digital Spy has given us ten hints from the anticipated upcoming episode.
Some of these hints are particularly juicy and include the whereabouts of two more classic Doctor Who characters. PLUS!!! We have some hints about the Doctor's regenerations!! YES INDEED!
1. Doctors 1, 2, 3, 4, 10 and 11 all make an appearance.
2. There's mentions of Axons, Azal and Aggedor.
3. "Smells like roast chicken!"
4. The Brigadier is still stranded in Peru, while Liz Shaw is on the Moon.
5. That's Groske, not Graske.
6. The Doctor doesn't have to be white. And he can regenerate more than 12 times - a lot more!
7. "You look like someone's baked you!"
8. Jo Jones (née Grant) has 7 children and (almost) 13 grandchildren.
9. The Doctor might never look back, but Sarah Jane has discovered some interesting things using Google.
10. "Accelerate the weave!"
