Butch must be over his issues with Riddler. Then again, he's got bigger issues with Penguin so it makes sense he'd side with Riddler for the time being. Tabitha isn't going to be too happy about this.
Why can't these two just get along? They could wreak more havoc together than apart, but they need to set their differences aside. If there was a showdown, I'd put my money on Penguin. Sorry, Riddler.
Penguin needs to stop complaining and start appreciating what Ivy has done for him. Yeah, we know she's still a child, but he needs to dig deep and find some patience.
