Red Arrow being the mole makes some sense, too. Here is my theory, and I will be taking a page from Oknight's book, if you don't mind. I am theorizing that somewhere along the line, Red Arrow was captured and tampered with--maybe even cloned and programmed with a mission.

The Light could not care any less about the team, because the goal was to infiltrate the Justice League--the big guns. That is where Roy comes in, and that is why he was so serious about joining the league, because it was the mission that was programmed into him. Robin and Aqualad were right in "Secrets", the villains could have simply shared notes with each other, and that Sportsmaster simply told Aqualad about a mole just to screw with the team so that they look from within. In reality, they were unimportant.

I just cannot figure out when he was programmed/cloned. It had to have happened sometime during his partnership with Green Arrow. It could have happened sooner even. Roy's bio states that he sought out Green Arrow to prove his skills and become his partner. Maybe he was a sleeper from the very start? You got to hand it to the Light to be able to plan so thoroughly.
