So after all, Fenchurch was neither insane nor lying. Sherlock was absolutely shocked because, if this whole Arthur Dent thing was real, then all the other things must be also real. All the flying business, falling and missing the ground, alien life, other dimensions, time and space travel… all of it!
Even with a man who looked exactly like John in his living room, and a funny looking man who claimed to be an alien, he was not willing to believe all of it blindly. His brain was desperate looking for something that would unravel this whole mess, a tiny piece of evidence that would make all of this clear. He couldn't stand the feeling of not understanding something and this strange group of people was driving him crazy. It was a blessing that Zaphod was not with them because he would have made Sherlock's brain explode.
Fenchurch rushed to help John who was still unconscious. Sherlock turned around and helped to wake him and carry him to his room. Then he returned to the living room and started walking around like a caged tiger.
"I think we should go now. Thank you for your help, Mr. Holmes" Said Ford prefect "And can you please lend a towel to our friend? I think she doesn't have one with her and it is extremely important that she carries one with her not that we are going to leave this planet"
"No! I need an explanation". Sherlock couldn't believe he was actually saying that, but he was desperate for a clear answer.
"Your Earth is standing in one piece and it is very likely that Vogons won't change this. You don't need to worry. And forget about the teasers. They just want to have some fun."
"What are you talking about?"
"They are not mean. Well they left me in this small and quite primitive planet or other version of it but don't worry about them. We have to go now. The Sub-Etha Sens-O-Matic says there is a spacecraft nearby, and we have to go, else we might be in this place for a long time again"
"So there are other inhabited planets?"
"Well, yes. Repeating the obvious and being so self-centered that you cannot imagine other inhabited planets… all of this it is normal for your kind."
"There is nothing obvious about this. We have no evidence of alien life and…"
"Says the man who doesn't even know his own solar system!" interrupted Fenchurch. "John told me about that"
"And did this John happen to be an ocean expert too?" Asked Arthur
"No, I don't think he was. Haha, I remember the good old Wonko"
"Stop! All of you. Just shut up!" Yelled Sherlock, who was… well there is not a word accurate enough to describe his mix of confusion, desperation and many other things, clouding the mind of the consulting detective.
"You should get a pint. It worked for Arthur" Said Ford
"Shut up!"
Sherlock started to arrange his thoughts. He knew that if he let this people leave the chances of finding out the truth about the picture and this Arthur Dent person were almost nonexistent. But this man, Ford, seemed to be really in a hurry, and Sherlock couldn't stand not understanding something as important as this.
"Do you have any salty snacks?" interrupted Ford
