You were one of Robin's rivals. You two never seemed to get along for whatever reason. However, Robin had come you you for help, for whatever reason.

Apparently, he had been fighting a criminal, and they got away. He believes you are the best person to help take them down. Despite how badly he doesn't want to ask for your help.

"Please, please, please, just give me a hand!! I don't like you, but your abilities would be so useful!! Pleaseeee!!"
