User blog:TimeImmoral/Ra's Is Coming...

So we know that Matt Nable has been cast as the centuries-old Ra's Al Ghul (though season 3 is supposed to be more 'grounded', so the chances are Ra's will not be going on 600), and that Ra's will be this seasons main antagonist (like Malcolm and Slade before him); my question is what causes Ra's to become the antagonist?

I think that he will go after Merlyn, and since Thea is with Merlyn, Ra's will use that against him or she will be caught in the cross-fire... This will also cause Oliver and Team Arrow to be thrown into the mix since Thea is his sister, which may cause a uneasy truce between Team Arrow and Merlyn (since only Thea knows Merlyn is still alive), will be very interesting.
