Iron Fist made a vague, noncommittal gesture as Roy apologized to him. [b]"What matters the course of a river, whether it is long and winding, short and straight, rough or smooth, so long as it arrives at the sea?" [/b] It was the sort of sensible-yet-nonsensical saying that Danny's masters had said to him when he had expressed concerns or questions of his own, and now that he found himself in a teacher role he felt somewhat obligated to pass them on to others. Besides, it got the general message across that he didn't mind Roy's lateness at all. 

[b]"If you like there might still be time to join them on the exercise, they might even do better with someone experienced to lead them, aside from a hard-light construct of Nightwing, anyways. But I think it might do them just as much good for you to observe them, get to know their strengths and weaknesses, figure out what it is they still lack. After all, I can train them, teach them, maybe even make them heroes, but I can't make them Titans." [/b]

He may have been the League's current pick to chaperon the team but he hadn't been on it originally like Arsenal and Nightwing had, after all. Even more importantly, except in certain cases he probably wouldn't take to the field with them on missions so it was imperative that at least one of the group's leaders worked with them in some capacity during their training hours, and from here Roy would be able to see the big picture of all their actions, or so Danny hoped.
