And I have been out of the loop for a while, I wouldn't want to get in your way or anything. But if something does come up I could always be your backup. Give Robin and the big guy a little break."
And then he slid up next to Batgirl, grinning from ear to ear, "Or I could just cheer you on from the sidelines. Though I left my pom-poms back in the 'Haven."
