When Bruce first took him on, being Robin had felt like the most important thing Dick had ever done. He loved being Robin. He loved feeling like he made a difference. He loved working alongside Bruce so closely. He loved being a hero. It was a lot of responsibility, and it was important, and he loved it.
But now, he's getting a little old for the role - he's taking on more of his own, independent work. He's starting to become his own hero. He's even started to ponder new costumes, new names. Bruce says this is a good thing! Dick's... having mixed feelings. But when Bruce found you, brought you home... well, those feelings got complicated.
Because the Bat needs a Robin, and you needed a family. He knew Bruce hadn't been out looking to replace him - heck, he knows he's not being replaced. There's a little jealousy, sure, a little bit of melancholy, but there's also some things a lot more important than that.
Because more than just the potential new Robin, you're Bruce's new ward. And that makes Dick your new big brother. And suddenly, being Robin no longer feels quite like the most important responsibility Dick's ever been given in his life. He's a big brother now, and that... that's really important.
So he's gonna try to be the best big brother he can possibly be. He's gonna take you under his wing, show you around. Help you acclimate to what's sure to be a lot of big changes in your life - he sure knows it was for him. The days after Bruce adopted him - after he lost his parents - were simultaneously the best and worst days of his life; he can imagine how you must be feeling. It's... a lot. He knows that. So he'll help you get through it. That's what big brothers are for.
"Mornin', kiddo." Dick flops down into his spot at the breakfast table, reaching to spoon some eggs from the serving tray onto his plate. Even on just any old day, Alfred always seems to go all-out. "Bruce is at the office today, said he's got some fires to put out. So it's gonna be you and me most of the day. ...That cool?"
