Yeah I laughed at Abel's House of Secrets, but yes, the Sandman references were also references to the 1960's-70's comic "House of Secrets" "hosted" by Abel, just like "House of Mystery" was "hosted" by Cain -- which cause Gaiman to make them supporting characters in Sandman.

M'gann sure has her own little freak world going on in her head -- We're going to see a lot more to that story, Does J'onn actually believe she's his neice? But I don't think she's the mole. KF could be the mole but the view of WallySoul inside the Fate helmet tends to rule it out. Robin could be the mole, but only if he's a magical duplicate, clone, or possessed by a demon and I'm sure Batman runs "magical duplicate, clone, possessed by demon" TESTS on him every night before bedtime -- we're talking Batman here.

So Aqualad. He could have been evil from the very beginning -- a deep cover sleeper agent placed by Ocean Master -- or (my bet) they replaced him with a clone when he was knocked out by Hook and Spider in Infiltrator.
