The female version of Sheldon is found in Mayim Bialik. Coming into public attention through her leading role in NBC's '90s dramedy, "Blossom", Bialik will portray Victoria on "The Big Bang Theory" in the May 24 finale.
According to EW, Victoria is Sheldon's love interest based on the eHarmony-type matchmaking service. Appearing on the last episode of third season, Bialik could be a recurring cast when the next season is premiered.
Victoria is not the only woman coming into Sheldon's life this season. Judy Greer has been tapped to be a well-known scientist whom Sheldon deemed as worthy to enter his bedroom. The character played by Greer will spend the night with Sheldon in the episode airing early May.
Beside the females, fans of the show will also be introduced to Sheldon's roommate, Sebastian, before he eventually settled in with Leonard. An actor is yet to be announced to portray this character. He would appear for the first time also in early May.
