Doctor Who: 10 Great Ideas That Went Absolutely Nowhere

Now, this is something that's completely fan-driven, and hasn't actually been explored, set up, or even hinted at by the show itself - at least, not intentionally. Still, it's a brilliant idea, so we thought it deserved a bit of shine!

It revolves around actress Michelle Martin, who holds a very special distinction in Doctor Who history. Not counting the two leads (Sylvester McCoy as the Seventh Doctor and Sophie Aldred as Ace), her character was the last person to speak in 1989's Survival, the final serial in classic Who before it was taken off the air.

What's extra notable about this is that her nameless neighbour bears a striking resemblance - both her appearance and personality - to Jackie Tyler, a character who was introduced in the next regular episode of Doctor Who in 2005.

It's insane to think that someone with such Jackie Tyler energy was the very last guest character seen in classic Who, and though the opportunity was there for the show to confirm that they're the same person, that opportunity has never been taken.

Obviously, this isn't a huge glaring flaw or anything like that, but it would've been a brilliant way to further strengthen the bridge between the classic and modern eras.

Plus, it even makes sense in-universe. Jackie was born in 1967, putting her in her early twenties during the events of Survival. The neighbour also lives in Perivale, London, not a million miles away from Jackie's Powell Estate home in the 2005 revival.

Alas, this is pure head canon for now.
