headcannons, let make it broad. tw: blood? mostly sfw, some nsfw but nothing too over the top...
interested in taking your blood and checking to make sure your healthy on both the outside and the inside
genuinely fascinated with your cuticles. he likes looking at the details in your skin under his microscope. he says that there's something intimate about knowing every inch about your partners body.
i think we can all agree that he is likely the most fitting candidate for a yandere (other than sniper) but i don't think he's one to be jealous often. if at all. he views scout as competition considering he's much younger, fit and conveniently attractive.
keeps an incorrect log of your health appointments, often writing of migraines, noise sensitivity and sore muscles. nothing that would catch the eye of the administrator but common enough to fly under the radar. these incorrect logs entail extra hours at the medbay that allow him more compensation and some lessons on anatomy or pharmaceuticals.
has a fridge filled with fruit juices and always offers you two after drawing your blood.
fingers you but with gloves on, even on your period. to him, it's just another day at work. (sorry)
archimedes has become to accustomed to your presence that the little dove doesn't fly away from you out of fear. medic, makes sure that he has plenty of seed that you can handfeed the bird. maybe that why archimedes is so unbothered by you.
medbay is always a safe space for you to unwind in, ludwig is unbothered by silence. it's a great opportunity for him to catch up on tedious and and onerous busy work required for him to complete every week.
random and unrelated headcannon, unfortunately, i can see him giving scout adderall, he just writes the prescription for it. likely asks for loyalty in return.
