This means the usual 22 episode season-run will now have 23 episodes much like other hit CW series that garnered enough good ratings to warrant extra episodes.
It's unclear as to whether or not the last 2 episodes of the season will be a 2-hour season finale with this news, so stay tuned for more info as it comes!

What do you make of having an extra episode of Arrow? Happy or annoyed? And do you want the episodes to air separately or as a 2-part season finale?
