Imagine: Theo after Mason gets shot.
"Theo!"You shouted from the end of the tunnel."Where's-oh fuck!"
You rushed over to where your best friend was slumped against the tunnel walls a bullet in his gut.
"Y/N!"Theo shouted as soon as he saw you, there was genuine panic in his eyes."He's shot!"
"I can see that, fleabag!"You shouted at you ex boyfriend. You bent down beside Mason and took his face in your hands."No, no, no, Mason, please not like this."
You composed yourself and looked at Theo.
"What?"He asked nervously.
You looked back at the blood spreading rapidly on Mason's shirt.
"Theo, take off your shirt."You spoke.
"What?"He asked shocked.
You turned back to him and held your hand."Take off your goddamn shirt, it'll slow the bleeding."
"Yeah. I know that."The chimera quickly pulled his shirt over his head and handed it to you.
You turned back around so you wouldn't have to look at his abs and be reminded of the reasons you dated him in the first place.
You tapped Mason's face to keep him awake before tying Theo's shirt tightly around your best friend's torso.
"You know, Y/N, if you really wanted to get me out of my clothes you could've just asked."Theo smirked at you.
You slapped him hard across the face."This is not the time, mongrel, now help me carry him to my car."
You put your hand under Mason's shoulder to hoist him up but before you could Theo picked him up with ease and threw him over his shoulder.
"Let's go."He said, Mason let out a loud groan as you and Theo took off running through the tunnels."It's gonna be ok, buddy."
You rolled your eyes at the thought of Theo actually being nice to someone. The whole of your relationship he had been nothing but a lying, power hungry, murderous tool bag. You'd come back to Beacon Hills to help with the war between the supernatural and the hunters and even though Liam and Mason had said that Theo had actually changed you had barely said two words to him.
***
On the drive to the hospital you were pretty sure you broke every speed limit there ever was.
"Wow, Y/N, you drive like a madwoman!"Theo called from the backseat where he was continuing to put added pressure on Mason's bullet wound.
"Shut up, Raeken!"You yelled as you got to the door of the hospital and skidded while slamming on the breaks.
***
You finally relaxed your head in your hands and elbows on your knees as Mason lay unconscious in his hospital bed. Liam's stepdad assured you he would be fine but you'd still been crying your eyes out for the past half hour.
You heard the door swing open but you knew it was Theo without having to look, you'd asked him to leave you alone but he kept coming in every five minutes.
"Go away."You sobbed.
You heard the loud screech of a chair being pulled up right beside yours.
"He's going to be fine, Y/N."Theo reminded you.
"I know."You spoke sitting up.
"Then why are you still crying?"
"Why am I still crying? Hmm, I don't know? Maybe because I've lost my whole family and half of my friends."
"You still have me."
"You?!"You looked at Theo with an amused expression."Do you really expect me to believe that you give two fucks about me after the way you acted during our relationship?"
"I know I don't deserve a second chance and that I've done some really really bad things but I've changed. I really like you, Y/N, and I want to be a part of your life more than anything. Please, let me be here for you."
You looked at Theo with tear filled eyes.
"O-ok. But if you ever kill another one of my friends you're so dead."
Theo nodded and pulled you to him, wrapping his arms around you as you fell asleep.
***
"THIS AGAIN?! SERIOUSLY?!"
You woke up to see Stiles, Mason and Liam staring at you and Theo.
"Stiles, shut up."Theo mumbled.
