I know I'm not the first person to do a Sherlock/Cabin Pressure crossover, but when I saw "Brilliant" on my list of b-words all I could think of was adorable Arthur. It may not be my best drabble ever, but I regret nothing!
"Honestly, John. With everything my brother has at his disposal, he could have splurged for a plane that's not held together with tape and wishful thinking."
The man who greets them reminds John of an excitable otter. "Hello, sirs, welcome onboard your flight with MJN. I am your Arthur and it is my pleasure to be your steward onboard today. Can I interest you in assistance with being onboard?" he says, with all the expertise of someone who's rehearsed the same speech many times and lost the flow of it halfway through. John smiles and hoists his bag towards the overhead bin. "Thanks, we'll be fine."
They settle into their seats but Arthur keeps hovering, like he wants to say something. Sherlock raises an eyebrow. "Can we help you?"
"It's just… you look very much like someone I know, but I can't place it. So, are you going somewhere exciting? Why were you in Fitton? I think it's lovely but mum says it's boring." The words spill out so quickly he looks as if he's about to trip over them.
"We were investigating a string of white-collar crime. I am a consulting detective and John here assists me. We solve cases that the police and government cannot."
"I hope you don't mind me saying this, sirs, but that sounds absolutely brilliant!"
