Fans of "Heroes" will be seeing a lot more of Robert Knepper in the fourth season as his character has been promoted to be a regular. Knepper joins the show as the new villain named Samuel who will be the centerpiece of the fifth volume, "Redemption".
Samuel was originally intended for six episodes only but he has since appeared in every episode of season 4. This was also the case with Zachary Quinto's Sylar who started off as a recurring role and continued drawing enthusiasm with his evil deeds.
Samuel itself is a ringleader of a traveling carnival that takes in people with special powers for unknown purpose. During his San Diego Comic Con appearance, Knepper said of the character, "Samuel seems to be the reluctant ringleader of this carnival. His brother just passed away."
On another casting news, "Heroes" has hired Tessa Thompson to torture Claire. The "Veronica Mars" actress will play an upperclassman name Becky whose job is to be Claire's sorority pledge master.
