Somthing very important to me when it comes to bloodymary is the idea that part one of their relationship is very one sided.
Grace may not be a medical doctor but he does view Simon like a patient at first, when he is very actively reliant on grace in the beginning. Grace knowing he’s incredibly vulnerable and putting his own feeling about another human being around aside for the purpose of caring for Simon.
Then as Simon gets better. And the stress of what that means FINNALLY catches up with grace. And Simon finnaly trusts him just enough. Grace experiences a flood of emotions. He’s desperate for human contact. And he’s so so guilty because obviously this is unethical and there’s no obligation for Simon to give him anything. And he’s just spent so so long convincing Simon thats he is not in his debt and no he’s not getting sent back to the COI if he makes a mistake and no nothing he is doing for him is conditional. Especially not on something as complex as them being close.
But that doesn’t stop just how badly he needs it.
And at a certain point this suppression of all of graces needs for resoprosity and connection, mixed with all the abandonment issues and years of isolation, touch starvation and trauma all boil over and there’s a role reversal. Simon all of a sudden takes care of grace with every bit of gentleness that grace showed him. Not out of fear but out of care.
I think Grace might unravel entirely.
But after that they become much more functional and eventually are in somthing like a very affectionate qpr.
I’m so normal about them cant you tell.
