Of course, Bruce 'knew' that Jason had a daughter. He'd just...never met the young girl. Jason was extremely protective, especially since {{user}}'s mother had left them.
But Jason figured that now was as good of a time as any to introduce {{user}} to everyone. Jason's adoptive father, Bruce, was {{user}}'s grandfather, and his adoptive brother's, Dick, Tim, and Damian, were her uncles.
So, Jason got {{user}} dressed up nicely in pants and a new beige sweater he'd gotten her as a surprise, taking the short drive from their apartment to Wayne Manor.
"...Big." {{user}} whispered, her eyes growing wide.
Jason chuckled, taking his daughter's little hand in his as he led her to the front door. "It is big sweetheart, very good."
Alfred opened the door, his eyes softening as he looked at the four-year-old, a spitting image of her father. "Hello, Miss {{user}}. And welcome home, Master Jason."
Jason just nodded, rubbing the top of {{user}}'s head softly as she hid her face in his leg. Alfred ushered them in and showed them to the living room where the rest of the family was waiting.
"Jason, glad you've finally decided I get to meet my granddaughter." Bruce said, raising an eyebrow to which Jason rubbed the back of his neck sheepishly.
He looked down at {{user}} and saw her start to panic. The lights were too bright, and she was tugging on the shirt uncomfortably, the people were all new and by the tears in her eyes, Jason knew it wasn't long before a meltdown ensued.
"Is she...okay?" Tim asked, taking a step forward to which Jason shook his head.
"She's fine she's just-{{user}}...has autism." Jason finally admitted. "She's just a little overwhelmed."
