None of the Titans knew Robin, Kid Flash and Speedy went so back. None of the Titans knew they were such good friends. None of the Titans knew that they had a bunch of home videos from when they were kids. None of the Titans knew they were about to watch previously mentioned home videos. None of the Titans knew that Robin, Kid Flash and Speedy were so different than what they seemed. None of the Titans knew they were each wearing their own mask.

Who said blind people can't kick butt?!
