The fact that there's LITERALLY A SLASH in the title makes me laugh. There's no way the writers did that accidentally.
I don't doubt it either, especially considering what is happening with Dick Grayson, the first Robin. Not only is DC embracing the all jokes his first name just begs for, there was Midnighter's recent appearance. Long story short Dick is now a secret double-agent whose face can't be seen by anyone outside the spy organization. Midnighter is a gay Batman analogue that was part of another company that got absorbed by DC. Midnighter figured who Dick was because he could never forget his ass.
That's remind me that I heard rumors about the writer wanting to start RH/Arsenal with a bang by having them playing a gay couple to get at a crime lord. :P
