The season hasn't even started yet, but The CW has preemptively decided to order more episodes of four of their returning series in spite of the fact that each of them already had a full season order. TV Line reports the network has ordered two more episodes for Gossip Girl and 90210 giving each series a 24-episode season while Supernatural and Nikita each got one more episode ordered for a 23-episode season. Apparently, this is an effort to keep the amount of reruns that show up during the mid-season to a minimum. If Vampire Diaries fans are wondering why more episodes weren't ordered for the series, the post-production process makes additional episode orders a little more difficult (not to mention expensive). Otherwise, if you're loving The CW and their ongoing series', this news should come as a treat.
