Harry Potter meets the Doctor: The Sequel

Boy-Who-Lived says: I LOVE this- it's amazing! Lol, you can just sit and talk to people you've never seen before in your life, guilt-free!

I'm a bookworm – get over it says: And you think that's a good thing? You're probably better sticking to people you DO know, like me and Remus. At least you know you can trust us.

Boy-Who-Lived says: Hermione, give it a rest, will you? I've got better thing s to do than listen to you nag.

I'm a bookworm – get over it says: I was only trying to be helpful. Anyway, I've got to go to work now, I'll talk to you later.

Just The Doctor says: Hello again! What are you up to now? I'm sitting in my Tardis in the year 5 billion, talking to you!

Boy-Who-Lived says: I'm supposed to be working, as my friend Hermione keeps telling me. And what do you mean you're sitting in your Tardis? What's a Tardis?

Just The Doctor says: Oh, it's my time travelling machine thing, don't think you'd understand. Humans tend not to.

Boy-Who-Lived says: I do understand time travel! Me and Hermione went back in time once in third year, to help save someone. Only we didn't use a- a Tardis thing, we used a Time-Turner instead, much easier.

Just The Doctor says: You mean, you literally turn back time? You humans are amazing!

Boy-Who-Lived says: Er, why do you keep calling me human? Are you not a human too?

Just The Doctor says: No, I'm a Time Lord, and I'm over 900 years old. Though I only look 30-something, which is great, lol.

Boy-Who-Lived says???

Just The Doctor says: Doesn't matter. Oh, here, I've got to go, the universe needs me. Talk to you later.

[Boy-Who-Lived has gone to get coffee

[FurryLittleProblem has just signed in

FurryLittleProblem says: Harry, did you ask that doctor about werewolf bites yet?

[Boy-Who-Lived has returned from coffee break

Boy-Who-Lived says: No, instead we talked about time travelling. He told me he has a machine called a Tardis.

FurryLittleProblem says: Owl me next time he's on then, if you're not going to ask him about it.

Boy-Who-Lived says: Remus, I hate to disappoint you, but I don't think he's that sort of doctor. He never talks about anything like werewolves.

FurryLittleProblem says: OK. Anyway, why aren't you working? It's not your day off, is it?

Boy-Who-Lived says: No, Remus, it is not my day off. You sound like Hermione. How's Teddy? What colour's his hair today?

FurryLittleProblem says: Teddy is doing very well. His hair is blue today. Don't change the subject.

Boy-Who-Lived says: I have my work sitting right here in front of me, just so you know, Remus. I fully intend to start as soon as I get peace.

FurryLittleProblem says: Put your Busy sign up and then get to it.
