Let's see...what is there to be said about Guy that hasn't already been said? Absolutely nothing.
Harley and him probably won't meet up, which is fine with her. She doesn't want to go to Arkham again!
Huntress, however, has opportunity to meet him. And punch him. A lot. Poor guy.
And Wonder Woman...tolerates him. She tolerates a lot of people, but you know...there has to be SOMETHING about Guy to like if he's a GL. She'll try very hard to like him.
