For a minute there I thought you'd having Doctor & Donna visiting the circus and meeting the young Dick Grayson... this is much better. Now all we need is to find out that in his youth Alfred was a member of UNIT. But budget cuts forced him out, and he went to America & met the Waynes.

I absolutely adore everything about this! Everyone was so in character - especially the Doc, 10/10 - and it's a lovely story! Well done!
Also, that "I own the monkey" line had me in stitches.

Can you write a sequel where a fully grown Bruce meets Donna and the Doctor again?

Aww! This is so sweet and funny. You got everyone's characters really well :-)

One thing wrong with this is the mention of the Flying Graysons, who were Dick and his parents. Dick Grayson isn't in The Dark Knight trilogy. In The Dark Knight Rises there is a reference to the name Robin, but that's it. Anyway, there are a few Doctor Who/Batman crossovers. Enter the words Doctor Who and Batman into Google.

This is perfect in so many ways, I can't even begin to list them. But I'll try. It's funny and sad and serious just like Doctor Who, like the Doctor and Donna. The Doctor making a spectacle of himself is very funny... and Donna being noble is just awesome.

This was pretty all around wonderful. Very true to the characters, very cute, very believable. I loved every word of it.

This is the best characterization of the Doctor and Donna that I've ever read. I could practically hear them talking.

Wow. Awesome.

*sniffles* Bravo, Donna! I miss her.

:'D Beautiful story. And I didn't know the Graysons were around when Bruce was a kid!

Sometimes I forget how much fun Donna was. And then I find stories like this one. Thanks

Look up Spacetime's Finest by Dean Trippe to see the Doctor with Batman and Superman. Also Doctor Who vs the Riddler by Dan Mcdaid. And a Dalek is seen in JLA Unclassified.

So sweet and touching.

You mixed the best of both stories - I loved it :)
