Sherlock sighed and ruffled his hair. He didn't usually care for dances, but tomorrow night was senior prom and he STILL didn't have a date. And he really wanted to go but didn't know how to ask his crush. Of course, he didn't know how to do anything around his best friend John Watson. He was contemplating sending back the suit Mother had sent when his phone buzzed.
Put on that suit and come outside.
Sherlock was confused. The number was blocked.
Who is this? -SH
Just do it.
Oh and bring a flashlight.
A very puzzled Sherlock wandered out side the dorm ten minutes later, wearing the suit and holding his portable flashlight. As soon as he stepped onto the sidewalk, a speaker was turned on from far upstairs. "Always" by Panic at the Disco started to play. Sherlock stared up, bewildered. How on Earth did they know his favorite love song?
He stood and smiled as the music washed over him. During the last repeats of the chorus, a flashlight began to shine in the distance, flashing out strange patterns of long shines and short. Morse code. It was a simple message, repeated over and over. "P-R-O-M" Sherlock spelled aloud. Prom. A figure, holding the flashlight, stepped into view at the end of the block and shone the light on himself. It was none other than John Watson. Sherlock gasped and smiled. As the final notes of the song played, Sherlock shone out a simple response.
Y-E-S.
