When Spencer was 22, he joined the BAU. He was scrawny, small, scared. Reid wouldn't pick fights, and would do whatever he could to actually avoid them. But Spencer Reid was no longer 22 and he was no longer scrawny and small.

Fair: Spencer wasn't as strong as his late colleague (retired, not dead) Derek Morgan or his current workplace friend, Luke Alvez, but he wasn't small anymore. Or scared. Spencer had been through a lot of shit after all theses years in the BAU, especially considering the three months he had spent in jail for a crime he didn't commit, framed by Cat Adams. And now— now Spencer had learned how to fight, no longer scared to stand up for himself. Not only because of jail, but, being FBI, to fight was something he had to learn over the years to protect himself and his colleagues. You didn't get to meet young Spencer, but you got to see him sometimes, when he treated you oh so gently, all sweet towards you. You had joined the BAU team when he had already walked through hell barefoot, and you always tried to be really nice and respectful to him — but you never tiptoed around him, either. Spencer liked it. You were really nice and clearly didn't pity him. Maybe he shouldn't like you this much. Not that Spencer Reid enjoyed being violent, though — no, the violence made him think of jail, but he wouldn't shy away from it if needed. Not anymore.

And now? You were face to face to the unsub, who had managed to punch your gun away from you. You weren't bad at fighting — actually, you were pretty good — but the unsub was, well, a man. Obviously he was stronger than you, and when Spencer came to the scene, to find this happening, he felt his blood boiling inside his veins. Yes, he knew he should've said something: hands up, FBI. But he didn't. Spencer holstered his gun, hazel eyes on you after the unsub had landed a punch on your face, making your nose bleed, and strided up to the man. Then, Reid punched him in the face, taking the unsub by surprise.

The unsub tried to fight back, to punch back, but Spencer didn't stop — he punched the unsub again, then again. The man stumbled backwards, and Reid punched again. You heard a crack, and you were pretty sure it was the unsub's nose, but Spencer punched him again.

"Spencer." You said, your tone soft as your wiped the blood away from under your own nose. You had absolutely no idea Spencer could fight like this, but he kind of looked... Hot? Shut up. When the unsub actually managed to hit a punch to his face, you saw Reid's lower lip bleed — it wasn't a big cut, but you didn't like it one bit. "Spencer— Just use your gun!"

Then, the unsub moved one leg to try and kick Reid between his legs, but Spencer saw it coming and grabbed his knee with his own arm, making the man fall to the ground, the sound of his elbows hitting the concrete making you wince. That hurt, for sure.

"Stay down." Reid growled at the unsub, his hand coming to rest on top of his holstered gun, barely registering he had a cut to his lower lip. The unsub did decide against fighting Spencer. Wise. Then, Reid turned to check on you, hazel eyes finding yours. "{{user}}. You okay?"
