Episode 2×05 of Arrow will be called “League Of Assassins" (and not "The Demon's Hand" as tvline reported a few days ago), confirmed executive producer Mark Guggenheim. As of today, we don't know if Summer Glau's character Isabel Rochev will appear in this episode.
It will feature a character called Awwal, a scimitar-wielding protege of Dark Archer Malcolm Merlyn. He is after Lisa.
The early title for the fifth episode of Arrow, "The Demon's Head", may be an indication that Batman's villain Ra's al Ghul will have some sort of impact on Starling City in Arrow season 2. Fans of DC Comics' Batman comic book series and Christopher Nolan's Batman Begins, know that the name Ra's al Ghul translates from Arabic to Demon's Head.
There's more: during the first season of Arrow, Malcolm Merlyn revealed that he received his training in Nanda Parbat, which is a fictional city of DC Comics that's been a stronghold of Ra's League of Assassins in the past.
And now a few words on this (new?) character named Lisa. In mid-June 2013, the producers of Arrow were casting for a new major recurring character/possible series regular for Season 2. Here name was Lisa and was described as "a mysterious woman with a tragic past". She will "wreak havoc on Oliver's heart and is equal to Oliver in every way".
Until now we thought that Lisa was just a code name for Summer Glau's character's Isabel Rochev, but the mention of Lisa in the snippet for episode 2x05 make me wonder and now I'm not so sure."Lisa" character could also have been the casting callsheet name for the new Black Canary, played by Caity Lotz. Or the role of Lisa has yet to be cast/officially announced. We'll see what Arrow writers have put together for us.
Season 2 is shaping up nicely, I hope everyone is as excited as we are to watch Summer Glau show her talent on Arrow, premiering on Wednesday, October 9 at 8 p.m. ET on The CW.
