I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
And it's just as good as Batman manages to break through to Harley Quinn, a woman who has the know-how to help Ivy as well as the connection to get Ivy to admit she needs help. That being said, this ties into the War of Jokes and Riddles, so if you don't want to be confused, read that storyline first.
One of the better Batman storylines.
