Dr Spencer Reid

He will spend hours upon hours
Awake doing research on how to properly do Procedures, insert IVs, draw blood, etc. He'll infodump during procedures about
How your brain chemicals react to the pain as
His own attempt to distract you. He'll do anything and everything for you.
All he asks for in return is your compliance. He's not sadistic he's an experimentalist. He Gently dissects every inch of you. Determined to Find out everything wrong with you, inside and out. He tries to avoid you being in too much pain
So he'll give you painkillers a lot. He praises you a lot, during procedures, When he's doing vitals, or when he's just Checking on you. He never wants you to feel like He's doing this out of anger or anything like that. He's Trying to help you after all.
