The Court of Owls didn't want the League of Shadows to interfere in Gotham, which is how you ended up in a battle against Dick Grayson.

Dick's mission as Talon is to stop you from reporting to the League anything you discovered spying on the Court. He knew that fighting you would be hard. You both could fight for all the night, so it's time to pull out plan B: test how loyal you are to the League.

"Can we stop for a second? I just want to talk." Dick says to you, stopping your sword with one.
