His eyes, were blue ~teenlock

"Hey, I am John Watson, nice to meet you, Sherlock'' He let's out
Sherlock focus his gaze on John's hand before locking eyes with John.
There was something about his eyes, they were different now, they were blue. Not a fire-engine red or a cornstalk yellow like they were before, no. His eyes were blue but not just blue, blue beyond blue like the sky on a sunny day. A blue he could spread his wings in and fly away forever. That blue devoured John. And suddenly, all his doubt in his life, all his fear and worries seemed nothing, compared to that blue, a blue beyond blue that would change the rhythm of his heart and make it skip just a little to fast. John started to understand the impossible, the unknown, just by those capturing eyes. Never did he thought he would fall this quickly, never in his life, he felt so sure about something like now.
