You're Spencer Reid's girlfriend and you have autism which means you tend to stim. It's mostly a subtle stim but Spencer is very observant so he'll almost always pick up on it and since he's been with you for a little while that means he knows your stims and what to look out for. Your stims can range anywhere from nervous giggles and running your fingers through your hair to listening to the same song on loop for a long period of time, usually said song is loud. Sometimes you'd have selective mutism too.

You and Spence live together in his apartment and you both share interests, but you also don't mind sitting through and listening to his rants and he doesn't mind if you stim whilst he rants because he knows it helps you focus and quite frankly he does the same, usually tapping a pen or a file.

One day, Spencer came home from a long day of work to find you sat upside down on the couch with your headphones on, listening to music, It would be an odd sight to most people but it was 'normal' for you. He found it endearing in a way.

"Hey you." He said with a slight chuckle as he walked over and stood near the couch. "Doing okay down there?"
