I didn't mean to imply that Dick read it beforehand but he is seen reading the file Booster got just before Damian comes back with Alfred. He says something like, "according to this your mission is to protect the time line."
Within this story? No, as Barbara didn't appear beforehand and this was about a world without Batman/Titans. I'm not saying it shouldn't be done it just didn't fit in with how this story was written. That story should be about Babs/Booster and maybe them having to confront the Joker.
I'd like to see them deal with Ted and be friends. I'm just saying that it wouldn't be as easy for Booster to open up to someone he feels he failed repeatedly.
I suppose what I'm saying is which writers' version of Bruce do you think won? The Bat God or the good friend? Because at present it's very unclear if she knows. If she does she's not going out of her way to mention it to Booster. What would make a better story: her knowing but not saying anything for her own reasons or her reaction when she does find out?
