I want to note that English is not my native language, so please go easy on me :) Also do I not own the characters, names and whatever that are mentioned below.

Ben stepped off his motorcycle. He stopped the engine from running, locked it, and took off the helmet that was a bit too small for his long face. He looked to the entrance of the building where they would start within fifteen minute with the script readings for season 4 of 'Sherlock'. People walked in and out. It was quite the anonymous place to start with such a long expected thing, but anonymity was all Steven and Mark wanted. Now it was quiet and there were no people photographing them, but within a few months he knew that that would be different, when they would be filming on set. He walked to the entrance, nodded to one of the people rushing out of the building and stepped inside. From the outside it looked dull, but from the inside it was very open; light came in trough numerous windows, and it lightened up the whole gloomy exterior of the lobby. He asked the receptionist where in this building he was expected ("3th floor, the first door on your right"), and walked towards the elevator. Once it's door opened, he stepped inside and pushed the button of the 3th floor. The doors closed, and he looked at his watch. He was running late. He needed to change in normal clothes before he permitted himself to attend the whole reading session. The elevator gave a loud 'ping' and Ben stepped out. He rushed into the bathroom that he noticed on his left, and changed his motorcycle suit for something more comfortable. He was about to step out when the door opened and Martin came in.
"Once late, always late" he noted.
"Thank you, and a happy new year to you too!" Ben answered with a smile. Martin looked up at him and started laughing.
"What is it with you and begin late, but not too late?! If I come in late, they threaten to cut my salary. Not that that is such a bad idea, but still…"
"It has everything to do with the way you react, you know" Ben answered. "First you need to look as if you have done absolutely anything that was in your power to try to be in time. Second thing is that when they have accepted that, you can come up with anything you want to say or do." He told Martin. "Oh, and third and most important: you have to look like me!"
"That's not the biggest problem. Maybe it's my length that does something to my amazing imitation of you…" he answered. "But what I do know is that if we do not return right now, they WILL make cuts in our salary!" and with that he turned on the spot and walked out of the door.
Ben followed him with amusement. He couldn't have wished for another person than Martin to be his co-star. It was always fun with him around. He crossed the hallway and stepped through the door he was supposed to have taken right after he stepped out of the elevator. He wasn't wholly trough it when he stopped mid track. The one person he had not expected to be here was staring at him with magnificent blue eyes and a fading laugh still on her face, probably from something the person next to her had said before he had stepped in. How could he have been so stupid not to read the scripts first, before he went here. He had absentmindedly browsed through them and this one major thing he had apparently missed.
He murmured a "Happy New Year" to everyone present, and took his place next to Martin. He felled he was blushing. Steven started to welcome them, wishing them all a happy new year. Ben didn't get much of what was said. He tried to remember what it was he had missed. He knew for certain that it was probably mentioned when they had gotten their scripts. He looked up to Steven, who was still filling them in in what they would do for the next three days. Ben didn't want to look to his right, because he knew that he would not stop blushing if he did. 'Shocked' was not the right word, but it was something similar that was getting to him. He tried to get his attention to Steven once more, so that he wouldn't miss other perhaps important things.
"We also like to welcome back Lara, who was so kind to accept a plea from Mark and me to please come back and play this fantastic role of Irene Adler. This time, Lara, I promise that you can keep your clothes on!" he said to her.
Everyone laughed. Ben tried, but it was no more than a smile that wandered off too quickly for his liking. He now took a glimpse at her. She looked good. Not as exhausted as the last time he had seen her. The simple blue t-shirt she was wearing complimented her figure, and the dark curls that danced around her head and shoulders fell perfectly in line with the movement of her head. The last time he had seen her she was tired, not in the mood for a good talk and it had been him that she wished not to see. But of all people, he was the only one around. It had been very awkward, and Ben felt the tension in his stomach when he thought about it. He looked at her again. Yes, she definitely looked better than the last time. There was more colour in her face and she was not trying too hard to smile. She just smiled, because she was genuinely enjoying herself, it seemed. He opened the script that lay before him, and started flipping through it. He did not know what he was reading. The only thing that was on his mind was that awkward moment and the accessory knot in his stomach. It had been his fault that is had come to that. He felt a sharp pain in his ribs. He looked up, startled, and noticed everybody looking at him.
"Sorry, what is it you said?" he asked Steven.
"Welcome in this room Ben. I was wondering if you would do me the honour of starting with reading?" the latter answered. Ben flipped back to the beginning of the script that was before him.
"Sure. Do I have to read the descriptions as well, or is it just about the lines?"
"Lines. I presume that everyone has read the descriptions before they got here…" Steven looked at Ben with a knowing look in his eyes. Ben looked away quickly and started reading.

As the time passed, he felt himself becoming more and more Sherlock. When they had done the first 25 scenes Steven cut in.
"Right, ladies and gentlemen. I think it's time for some coffee and tea. On you go!". Ben looked across the table to Lara, but she had already stood up and walked out of the room. Ben stood up as well, and made a move to walk into the same direction Lara had disappeared, but was stopped by Mark.
"Ben, if you have a minute?" he asked, and gestured towards the seat he had just stood up from. Ben sat down with a sigh. He locked eyes with Martin and mimicked him to not wait for him. When the room was empty Mark started speaking again.
"Listen, I don't know what has happened between you and Lara, but please, for the sake of everything, put it aside". Ben looked up abruptly.
"I'm sorry, but I have no idea what you're talking about…" he tried, but he knew that almost everybody in the room had seen his shocked face when he had noticed her sitting at the table.
"Ben, come on. Like I said, I have no idea what is going on or what happened, but I need to know that when the cameras are rolling you two can come up with that beautiful chemistry again. I don't want two people trying too hard. It is something naturel. That's what Steven and I have based the scripts on! You don't have to tell me, or explain anything, but just make sure that when someone yells "Action!" there is something to look at…". Ben thought about it for a moment.
"Mark, I can guaranty you that when someone yells "Action!" I will do my very best to act the hell out of your beautifully written script. Just trust me in this, OK?" Mark nodded.
"Well, come on then. The tea is waiting…" he replied with some uncertainty in his voice.

It will continue :)
