Bruce knowing he and Dick have a special relationship but not really characterising it as father and son because it has been so long since he had a father figure who was willing to acknowledge it in a positive life. Alfred didn’t acknowledge it at all. He was Bruce’s employee, not his father. Ra’s wanted to fill the boots of Bruce’s father in a way that tainted what it meant to be a father.
And Bruce figures that mentor and apprentice is enough. Mentors protect. They guide. Historically apprentices lived with their mentors too. And that’s what he is for Dick: a mentor.
And then there’s a horrific crime and kids are involved and thankfully Dick is at home with the flu so he doesn’t have to see it. But some cops are talking and one of them says that all he wants to do is go home and hug his kids. And Bruce realises all he wants is to go home and hug Dick, to hold him and know he’s safe. And Bruce realises that Dick is his son in every way that matters.
