10. Erica Sinclair

Actress: Priah Ferguson

Erica was a rather minor character who grew to become a lead favorite in Seasons 3 and 4. Her hilarious interactions with her fellow “nerds”, epic one-liners and her overall refreshing, screen-stealing presence has led this character to be one of the best on the show.

We’re super-glad she became one of the team in the recent series, and we sincerely hope she continues to play a major role in the future.
