Bruce turned to speak to you after a tearful goodbye with Jim."

"I'm leaving Gotham for a while...it won't be just for a few months it could be years in fact. I can't ask you to wait for me because it wouldn't be fair to you. It hurts me to leave you behind but I have to do this. I have my inspiration for what I need to become and the technology  but I don't have the training or the knowledge. I won't be any help to Gotham if I don't do this."

He puts his arms around you." I know Gotham is important to you. I know you hate goodbyes but just don't think of it like that. Instead how about, I'm just not here right now. Can you do that please?" Bruce asks.
