Imagine Draco and Harry have been dating a while and they are at Friday night dinner at the Weasley’s. Fred and George are reminiscing about that one really epic blanket fort they built when they were eleven, and Draco leans into Harry and whispers “what’s a blanket fort?”
Ron overhears. “You’ve never built one?” he asks. When Draco shakes his head Ron exclaims “what the fuck?” and is promptly whacked on the head by Molly. “Sorry Mum, but he’s never built a blanket fort!” And Molly gives Draco a sad look because some of her happiest memories are from watching all her children working together to make forts.
Ron stands up, all purposeful and determined, and declares that they are building a blanket fort tonight and herds everyone into the living room. He instructs everyone on their roles and sends them away to collect blankets from around the house and as they head up the stairs after Ginny and Hermione, Draco says to Harry “this is madness.” Harry just grins because Draco is all but dragging him up the stairs in excitement.
The fort is enormous and takes up the entire space of the living room, it looks like a giant canopy of faded patchwork. Draco makes a face at having to sit on the floor at first, but then he crawls inside and settles on a pillow beside Harry, linking their fingers together and looking up at the roof of their creation.
Fred and George disappear and come back with Firewhisky and Molly sends in snacks, and they spend the whole night drinking and laughing in the fort until they all fall asleep, and Draco doesn’t care that he’s 24 and probably too old for this - he is pretty sure it’s one of the best nights of his life.
