User blog comment:ZombifiedRipper/Possible Chance that Ra's Al Ghul May Appear/@comment-71.61.223.30-20131101005056

A lot of uneducated fans here. Ra's is Ra's he's not Slade, or Merlyn. Merlyn referenced meeting a man in Nanda Parbat which is where Ra's is known for being. He said that (Ra's) showed him the light in what to do. To destroy the glades and rebuild(much like how Ra's in 'Batman Begins' wanted as well as Bane in 'The Dark Knight Rises'. His black attire matched that as the assassin that showed up with the Canary(confirmed Sarah Lance). Confirming the involvement of Ra's and Sarah.

All that Said Merlyn was a member of the League of Shadows in the comics so that should be no shock. Sarah being trained by him is a bit of a shock, meaning he could be this season's "big bad". Can't wait to see him and Slade Wilson in the present. For now let's see what they do with Brother Blood.
