I love that you asked me this because I was JUST frantically discussing that with @badnewbie. I would never in a million years have guessed that DC's first acknowledgement of Riddler being bisexual since Valentine's Day would be five months later in The Harley Quinn Show trailer, but in retrospect it makes so much sense that I don't think it could have been anything else. Honestly, as a named reoccurring supervillain character, Clock King is a million times better than I ever thought Edward would get for a male love interest (I assumed he'd be getting one-off unnamed civilians at best for the next quarter century). Disclaimer, however, that this IS the show that hatecrimed me by forcing me to watch Poison Ivy date Kite Man, so I'm sure however they handle it will be physically painful to watch.
