okay, fanfic idea:
I've been reading a lot of de-aged Bruce fanfics recently, and I thought of something. Instead of Bruce being turned into a younger version of himself that the family can interact with, they react to how younger Bruce used to act and who he interacted with.
Maybe Harvey Dent got a video camera for 15th birthday and he started filming interesting/funny moments in his life, usually with Bruce as his unwilling co-star.
Maybe Harvey stopped making videos until he was older and ended up giving the old footage to Bruce for christmas, sometime before he became TwoFace.
Maybe Bruce kept the footage in the attic all these years, locking away those memories for good.
Maybe Dick went looking for an old toy or poster that he wanted to show Tim, and found a box labelled "1987 - 1995" (aka. Bruce when he was 15 to 23).
Maybe he showed his findings to the others and they asked Alfred to play the recordings for them (after Bruce leaves for a mission related to the Justice League).
The videos would always be centred around Bruce and Harvey, but other - both familiar and unfamiliar - faces would occasionally pop up.
What do you think?

"None of them have a date written on them, just titles." Dick pointed out while sorting through the cassettes.
"Who cares, just pick one and get on with it." Jason replied, still grumpy from being called back to the manor earlier.
He was seated in the armchair where Bruce usually preferred to sit during movie nights, but with their father being away he decided to take it for himself. Tim, Cass and Damien were all on the big leather couch, with Cass squished between her brothers.
Finally, the oldest of the group (not counting Alfred as he was busy cooking dinner) picked a tape labelled "Honey Bees", put it in the player and took a seat on the floor in front of the couch.
The screen lit up.
[ A seventeen year old Bruce was making tea in an unfamiliar kitchen. The person behind the camera was trying to hold their laughter, causing it to shake slightly.]
"What the fuck?-" Jason croaked out, not that the others could blame him. The young man on the screen - their father from 20 something years ago - looked nearly identical to Jason.
Bruce had jet-black hair, but a good chunk of it was dyed white. He wore a black sleeveless turtle neck, along with matching black trousers and combat boots. He was still muscular, but he hadn't yet gained the amount of body mass he currently had.
The teen was glaring at the cameraman, though it lacked any heat. His frown, and his eyes, were the only things that reminded the group that that was in fact, not Jason Todd.
"That's so weird dude."
