A silly thing for our OCs, but who would be the best behaved in the Doctor's to the worst. (Like regular checkups, nothing too bad.)
SDKFGHSDKFJ OKAY LET'S GOO
Morphine - as a medic himself and being dead inside he really doesn't care what's being done to him. Easiest to deal with. You could tell him he needs a surgery and he'd just shrug like ok whatever, now or do I have to come later?
Renfrew and Breeze - good and unproblematic babs. Don't like needles and painful stuff but won't show it (may complain a bit with Breeze may try being a bit flirty to lighten up the mood). It's no big deal but they do appreciate hugs afterwards.
MiniMint - she's fine, real good bean, deserves a sticker. If there are needles involved it will make her uncomfortable but she knows how to behave. Feels best if she's held tho 'cuz she's afraid she'll involountarily twitch and make things worse. But dw, that never happens. Probably won't ask for it but really appreciates some sweets afterwards. Get her some enerjuice or enerjellies. Distracting her withmaking her nerd out about rocket science will make her forget about any unpleasanties just as well.
Taffy - uhh are we talking before or after the trauma?
Before - he's flirty. Good bab, maybe a bit annoying if you have low tolerance for flirty goofballs. Theatrical drama queen when there's needles involved. Tries to cover up how much he doesn't want it. He's gonna need help calming down. It's not that he'd escape but he needs to be held for comfort. Panics more than it's worth. Afterwards needs to be taken for ice cream or else will sulk for the rest of the day like an offended princess.
After - needs his trinemates to hold him. Preferably restrained in a blanket burrito 'cuz he really doesn't like to be touched. Even for the slightest checkup he needs to be held close and softly talked to. And it's not even being a drama queen about it, the distress is real. Good thing at-home checkups are a thing 'cuz the poor bean wants to avoid any contact with anyone other that his trinemates and close friends. Good thing he has 2 medics among his frind group. Luckily eventually he improves to the point of being like before or even like Mini.
TerrorRain - will complain and be a bitch 'cuz he doesn't need no check ups. Will refuse to have stuff done to him, may need to be dragged in by someone strong enough even if it's just a check up. Doesn't fear needles but will not follow doctor's recommendations unless it later ends with shit going badly and him thinking "Uhh... I... probably should've listened." Much better chances of getting him to cooperate if the medic in charge is not Morphine. They're gonna be extra jerks to one another.
StrongSpark - he's a child of special needs. Can't understand what and why is happening around him and being blind surely doesn't help. Sure he spends a lot time at hospitals but that doesn't make him any less distressed or more used to it. The same procedures that normally take just a while stretch into hours as he needs a lot of preparations and comforting. And often some sedatives when he gets muscle contracture malfunction out of stress. Requires the most time of all listed here but is also most innocent. Sparky is the only bot Morphine has so much unending patience for. He gets lots of love from both his parents (yes, even Terry and Morph are capable of love). Years later he improves and manages to understand that the pain is usually temporal and just letting it happen will result in less of it. Oh and also he learns to talk a bit!
