Bruce switched to his normal voice; not the one he used as Batman, or Bruce Wayne, but the one he used around friends and family. He wasn't sure if it was meant to further disturb Hal, or put him at ease, but Bruce was done pretending with him - that was the point.
"She knows,"he confirmed, although it hadn't been a question. "I believe she first suspected about six years ago, when a mutual friend of ours was severely injured, but I'm not certain. We've never discussed it. I met her and Dinah Sr. when I was twenty-five. Dinah was nineteen and newly married. Ted Grant trained me - in costume, more or less." Bruce had been so serious, so intense then, but some of his best memories stemmed from the conversations he had with Dinah's mother, who understood him just as much as she thought he was crazy. "I believe Senior knew, even then."
Why. When it came right down to it, Bruce had never questioned whether or not he should. The time was right. "Because you love her," he said flatly. "Because you'd do anything to protect her, and you trusted me to keep her safe without knowing I would have done it anyway. No, I didn't know then," Bruce lifted a hand to stop the question from coming. "But I did. What Dinah and I have isn't about the promise I made you, but I owe you the courtesy of letting you know that I will do everything in my power to look after her, and I trust that you will do the same. To prove that, you need to know I'm capable of doing it."
And he needed to make peace with Hal, Dinah's best friend. His relationship with her would quickly find trouble if the two men were frequently at odds and of all the things they didn't have in common, there was one very large thing they did - Dinah. Bruce tugged off the gauntlet and glove of his right hand and extended it to Hal without a word.
