The Doctor never actually said they could read through the contents of the box, but somehow it was silently agreed upon, and soon Amy and Rory were both examining them, munching on jammy dodgers, and eventually, even the Doctor joined in too, although he tried to steer away from anything remotely sad, or personal. When Amy unearthed few scribbled lines Adric wrote shortly before his death, the Doctor quickly turned her attention to a photo of him with Elvis Presley.
Then Rory asked, "Doctor, who's this postcard to? It's addressed to Dad..."
The Doctor glanced at it.
"Me," he announced, laughing at his friends' astounded expressions.
"You? A Dad?"
"Why not?"
Very much intrigued, Amy peered over Rory's shoulder and they read it together.
Hello Dad!
I suppose this postcard might be a bit of a shock, seeing as you thought I was dead. Well, I did die, but it seems I'm enough of a Timelady to revive myself after all, so I stole a rocket to see all the planets and civilisations you told me were out there for myself.
Oh Dad, it's all even more amazing than I imagined! There are so many places to see and adventures to be had; the universe is so large that you can go on exploring forever. I got this postcard on New Earth which I visited recently and I had to escape from cybermen in New Turkey. Donna was right – there is an awful lot of running involved!
I wish we could have said goodbye, but I want you to know I won't forget what you taught me, about fighting for justice and peace not gain or glory, and the value of human (or otherwise!) life. I'll see you soon, I'm sure.
Love Jenny
"I can't really imagine children growing up in the Tardis," remarked Rory.
"Sadly I was robbed of normal parenting that time, like you were with River."
"Wait, there were other times?"
"Oh yeah," the Doctor affirmed. "I came to earth with my daughter Susan a long time ago."
However, he offered nothing more, so Amy moved the conversation back to Jenny.
"Do you think you'll see Jenny again?"
The Doctor smiled. "I hope so," he said. "I hope so..."
