Yesterday I was just thinking about Irene Adler's line 'Mr. Holmes, if it was the end of the world, if this was the very last night, would you have dinner with me?' and what if it was the end of the world and the Doctor and Amy would come to seek Irene and Sherlock's help. Would Sherlock help the Doctor?

Irene Adler: Mr. Holmes, if it was the end of the world, if this was the very last night, would you have dinner with me?

Mrs. Hudson: [off screen] Sherlock!

Irene Adler: Too late...

Sherlock Holmes: It's not the end of the world, it's Mrs. Hudson.

Mrs. Hudson: Have you not heard the doorbell? This man and his companion are looking for you. Well, I'll be downstairs if you need anything.

Sherlock: Thanks Mrs. Hudson. (looking at the tall man who is wearing a suit with bowtie and to his red haired companion) And you are?

Doctor: well, I'm the Doctor and this is Amy Pond.

Amy: Pleasure to meet you Mr. Holmes.

Doctor: And I assume you are the great detective, Sherlock Holmes. (then, looking around the apartment) Where is the lady who were you just talking to? (Sherlock's bedroom cracked open)

Irene Adler: So you are the Doctor.

Sherlock: How did you know him?

Irene: I had a client who said wonderful stories about The Doctor. I thought he was jesting.

Sherlock: Okay let's stop this chit chat and let's get to the point. So you're a Doctor. Doctor Who?

Amy: Don't get him started.

Sherlock: Fine, what do you want?

Doctor: There are some unusual things going on in London right now and only the two of you can help us.

Sherlock: What is this bizarre situation you're talking about? Lestrade would've called me if he finds things that he can't solve.

Doctor: No Mr. Holmes it does not involve the things that you have solved before.

Irene: Then what it it then?

Amy Pond: You wouldn't probably believe us but...

Doctor: It involves extraterrestrial species..

Irene: Extraterrestrial species? you mean aliens?

Sherlock: Aliens? Well this is ridiculous.

Doctor: I know you don't believe in this things but you have to see it. Your help would make this easy for us to end.

Amy: Please Mr. Holmes you two can help us. Or else...

Sherlock: Or else what? The end of the world? hahaha This just a wast-

Doctor: Yes, it would be the end of the world (he interrupted the detective)

Irene: The End of the World? (looking at Sherlock)

What do you think? Please R&R…
