I know it's kinda crappy, but I did my best! Also I extended it.
If Dick was de-aged, age being 16. How would they react with him only three feet away sleeping soundly in his bed all of them waiting for Dick to wake up? Will He remember them? They hope he does, but obviously he won't.

1.)
Bruce kept a straight face the entire time, only acknowledging his other sons for a brief moment when they entered the room were his eldest son lay sleeping. He'd gone over his brooding thoughts for hours on how to explain why the boy was here and why he meant so much to them. Dick was too pure and too kind for his own good. The easiest way would be to lie if Dick lost his memories which made the acrobat a liability.
-Bruce chooses to lie for the family and Dick.-
2.)
Jason clenched his fists as he looked away from the person lying in the bed who used to be his older brother and who was also not his older brother anymore. He looked the age of sixteen or fifteen now since those stupid scientists had done tests on him. Horrible tests, but none of them did real damage except for the permanent memory lose. He mind wiped clean of who they were, what they were... what he was. Nothing survived and the only thing he knew is that his name was Richard, but that was all he knew. There was nothing left to salvage or to regain except the memories those assholes had warped Dick's mind with. Jason couldn't believe the men were feeding Dickiebird LIES and now he's going to be feeding Dick lies too.
-Jason chooses to say nothing for fear hell only make matters worse like the others are sure to do.-
3.)
Tim gulped down the sense of dread and put on a blank but distant face. He hated that Dick couldn't remember him. Mainly, because even after being such a brat to Dick the older still kept in touch with him. Always visited him and even comforted him in his darkest moments, but now he wasn't going be able to do that for Tim anymore. He may have thought he could live without Dick's influence and affection, but not now. Not when Dick won't know him.
-Tim chooses to lie to protect his once eldest brother.-
4.)
Daimain looked at his eldest brother who was now his age and gritted his teeth. The disgusting scientists touched his Grayson. That's right, HIS! He'd spent most of his life with Richard and now he's going to have to lie about himself and hide all the secrets he'd told Dick years ago. All because of that psychotic science junky's had their eyes on the Dick for the longest time. The assholes had won in corrupting the family more then a little and Damian wanted them all dead.
-Damian plans to kill or torture Dicks attackers, but might lie to protect him.-
5.)
Even Alfred who was standing near the door felt like something was ripped from his heart.
-Alfred chooses to pray in the hope that he doesn't have to lie to Dick.-
They all look a the sleeping boy sadly, but gasp when his eyes flutter open. Those clear blue eyes roam around the room innocently and in a oddly relaxed manner. Everyone stays silent.
Who's going to lie first?
