I do hope if this does happen we can get a Nightwing vs Deathstroke scene. The younger fans may not remember the rivalry but it was one of my favorite hero/villain relationships when I was growing up.
I would love to see that too. Though, I may laugh out loud at how silly Two Face/Deathstroke looks! I'm just glad I wasn't drinking anything this past Wednesday when they revealed that. I couldn't stop looking at his face and laughing. Poor decision by the writers on Arrow.
