I have a little headcanon living in my brain but i cannot write so i will leave it to you people…
Basically at some point one of the batkids find a photo album in some old storage elsewhere in the manor.
They obviously decide to open it, family bonding all that jazz.
But the pictures are clearly pre-Bruce, Thomas and Martha on dates, pictures in the manor gardens, Polaroids and photo booth strips of themselves stuck in.
All very cutesy.
And then Alfred is there, polaroids of him in the kitchen, dancing with Martha, gardening with Thomas, frowning at the camera as he sits in the library.
But then slowly the photos are getting more intimate, Thomas and Alfred with their cheeks pressed together grinning at the camera with lipstick stains on their faces, Martha laying against Thomas’ chest in the bedroom, Thomas’ head in Alfreds lap.
They cant stop turning the pages, more and more throuple-y adorable photos, finally one with Thomas and Martha on either side of Alfreds cheeks, in marker underneath ‘our Alfie’.
Obviously its chaos, blah, blah, blah i think theres a fic in there somewhere
