Ok, but I reached an eureka moment and I need someone to hear me out: will x theo could be potentionally wholesome. Like, you have just some guy who's dating this perfect dude and Will is aware, hell he is probably used to people asking him how he bagged a baddie like Theo, all meanwhile Theo is Will's number 1 fan/supporter, he's absolutely smitten for this wet dog of a man. Their dynamic has so much potential.
The fun thing about these two is that typically Will’s presence adds a sense of dedication and loyalty like no other to ships, sort of like Annabel in his weird little way that he genuinely WILL GO LEAPS AND BOUNDS. But Theo is dramatic, a bit of a typical sort of man, polite and witty and trying to establish his own life after his father’s while I’d imagine ending up a bit as his father’s golden child. I can imagine looking like a man who wanted the power, the presence that comes with dating this prize and top tier rich boy, entirely regular seeming and with little connection to wealth. But I doubt Theo could see it that way. Because Theo would see Will’s weaseling into his heart as evidence that he is loved, and he is more, right? Theo is rich and high class with his manners and music and the skills and life of what a man of the era should be, but Will loves him and that can be a jarring realization when he’s used to adoration for other reasons. Theo would LOVE him like that, and Will would do his best to try and change, adjust to his environment: be a richer man, learn how to live the life, try to tame his hair. But Theo would likely laugh at him in those fancy clothes, loving and telling him it looks so wrong. Theo would catch Will returning to the grounds or the garden, attempting to get fruit from their tree, and he’d fall in love again with the quiet thought and consideration and little moment of peace that Will gains. He’d love Will’s love, his care and attempt to learn and fit in, and his appreciation for small things. He’d love how he ACTUALLY LISTENS beyond the sound of money in his pocket or fancy clothes. They’d just love.
