Episode #8-15: Title Unknown
UPDATED 11/14/08: Lois Lane (Erica Durance) returns in this episode.
OH THANK GOD! I figured that she would be back but you never know with SV. 4 was bad enough, if they had actually pushed it to 5, I would've hurt someone!
Now we all just have to pray she's in every episode from then till the season finale! :D
