John's point of view:
It was a long, arduous day. John was glad it was finally over. With his sister, Harry, in St. Bart's hospital for drinking too much, John savoured his precious moments to himself. But not for long. Mike, his best friend waddled up to him; his chubby, clammy hands patting johns shoulder. John flinched.
"Hi John! Ready for the new exchange students? I heard Greg saying they're from Spain!" He beamed.
Greg LeStrade was quite an honest bloke but with a cheeky and sarcastic streak to him. John was debating whether it was true or not. But in his deep thoughts he'd realised he didn't reply to Mike.
"Oh, um yeah, I guess." He was about to give Mike some small talk until he was interrupted by the new kid who had moved here about a week ago.
"Excuse me but do you know where the toilets are?" His request was cold and sharp.
"2 rights then on the left."
"... Thanks" The student replied reluctantly.
He scuttled up the stairs and vanished to find the toilets whilst John turned to Mike.
"Who's the newbie?" John asked. His head tilted a fraction.
Mike's answer was stiff. "His names Sherlock. Sherlock Holmes."
