Imagine Stiles goes blind.
It takes a while for the pack to adjust but they do, making sure to say things out loud instead of nodding or shaking their head, and making sure that Isaac stops Stiles before he walks into something that could hurt him instead of sitting back and watching on for a few laughs. They still occasionally slip up and ask him “Did you see that?” to which his only reply is to blankly stare at them.
A lot of the time he makes the best of it, often teasing Derek about how he can just imagine him naked all day every day and he doesn’t have reality to break that illusion.
Stiles adjusts to his new way of living, learning how to memorise things in his house and walk about them and when he needs to read something, Derek reads it to him (stories, case files, the latest supernatural research, everything).
On their wedding day, Derek forgets his tie and has to run to Scott’s to get it (Because Scott was in charge of the suits and Cora was too busy trying to get into her dress to make the run for him). When he gets there, Scott tells him to wait in the door while he runs to get the tie. Stiles hears him and shouts hello. Derek tells him “It’s bad luck to see the groom before the wedding.” To which Stiles teasingly replies, “Then it’s a good thing I can’t see you.”
During their wedding, Stiles and Derek wrote their own vows about how they don’t need to look at one another in the morning to know that they’re waking up to each other, they don’t have to see one another to know that the other is there for them and they don’t have to share loving gazes at the alter to know they are standing before the man they love.
When Stiles and Derek adopt a baby, Stiles is terrified and heart broken. He’s scared that because he can’t see he won’t be able to care for the baby but he does his best. And he’s heartbroken because he never gets to see their child. Except for one day, when Scott heals his sight just long enough that he can see the smiling face of their baby and then look up at Derek’s loving gaze. The vision doesn’t last long, but that’s perfectly okay because now he can hold onto that image forever.
