User blog comment:Eobard95/Was Shado's mother Talia al Ghul?/@comment-27700324-20170320045408

Oliver isn't Batman! they won't be together. The only reason that they have the League is because they were involved with Black Canary in the comics and Arrow uses that stuff. Seriously, same thing with everyone wanting Robert Queen to be in Flashpoint. The actual Flashpoint had Oliver as a weapons dealer known as the Green Arrow, he wasn't replaced by his dad like Batman.

On other notes, Talia being Shado's mom is possible, but we have no evidence. Also Shado's sister was put in the show to mess with the fans. Just admit you were caught off guard when you saw that episode for the first time.
