December 22nd
The Doctor was in the console room, while Amy and Rory Pond were asleep. Which gave him time to reflect on his past. Not like he had much of a choice. He didn't really need sleep, so there wasn't much to do. And he needed to be busy, constantly needing things to do to not get too deep in thought about his past and get even more depressed. Even little things like, fix the TARDIS or TRY to upgrade her. Sometimes even try to fix the chameleon circuit when he was having an extremely rough day. But today, nothing could get his mind off of December 22nd. Even going to this new planet with Amy and Rory where cannibalistic, alien tribes tried to kill them couldn't get his mind off today.
The worst day of his life.
The day he got separated from Rose Tyler.
It's all your fault. You could still be traveling with her today if it wasn't for you!
But what would you do if she died? She's happier with the clone in the parallel world.
How do you know that?! She could be dead for all you know!
It was as if a war constantly played in his mind with him and his subconscious.
After the Time War on Gallifrey, The Doctor was a bitter shell of who he was.
And then he met Rose.
She made him feel love like he hasn't felt in hundreds and hundreds of years and he slowly grew back to the man he was before The Time War. But of course, that love didn't last. It never really seemed to.
He blamed himself. He always blamed himself.
Why weren't you more careful? The thought that reflected in his mind constantly that caused a feeling of guilt that panged in his heart nonstop.
Rose Tyler made him into someone who cares and not someone who doesn't. She forever changed him into who he is today.
She has the duplicate, her mum, her dad…She's happy. Just like everyone is after traveling with me…
You wouldn't have never met The Ponds if you hadn't stopped traveling with her. You probably wouldn't have met Martha. Or Donna.
Now here he was, on December 22nd. Reflecting on the past. And wondering one thing.
What happened to our forever?
