When "Chuck" returns with a new episode next week, all eyes will be on Sarah as her past comes back to haunt her. A preview for the episode has been made available, revealing that Sarah is forced to confront a secret from her past. While Chuck urges her to let him help, she feels she must do so alone.
Several flashback scenes involving a baby and Sarah's mother, Emma, are included. Previously, executive producer Chris Fedak teased that "Sarah and her mother share a mystery that has forced them to be apart." On what to expect from the episode, he said, "After this, you will know Sarah as a different character."
"Chuck Versus the Baby" will air on December 30. A synopsis for the episode suggests that Sarah will come face to face with her original handler, Kieran Ryker, and she fears that he will harm those closest to her, including her mom. Former "Charlie's Angels" star Cheryl Ladd guest stars as Emma, while "White Collar" actor Tim Dekay plays Kieran.
