With the second season of Star Trek: Discovery premiering next week on CBS All Access, new cast member Ethan Peck has shared some insight on his portrayal of the iconic character of Spock in the upcoming season.

Previous promos for the series revealed that a younger incarnation of Spock would join the crew, with Peck's depiction of the fan-favorite character significantly more emotional than his original portrayal by Leonard Nimoy on the original series and eight films. In a new interview, Peck describes his version of the character as one of self-discovery from a traumatic event, resulting in visibly more volatile emotions.

"I view this time in his history as an opportunity for us to explore Mr. Spock's genesis. It's during this moment that he reconciles his human and Vulcan [mixed heritage]," explained Peck in an interview with TV Insider. "We see him sway between extremes of emotion and logic."

trailer for the upcoming season released last month featured Spock engaged in an emotional argument with his adoptive sister Michael Burnham, catching longtime fans of the character off guard.

"He's absolutely more emotional than we've seen him before," continued Peck. "[Those emotions] erupt from deep within him, triggered by a traumatic event. He's dealing with his human side for the first time since childhood, a process that is essential to his development."

Returning on Thursday, January 17, on CBS All Access, Star Trek: Discovery stars Sonequa Martin-Green, Doug Jones, Anthony Rapp, Shazad Latif, Mary Wiseman, Wilson Cruz, Mary Chieffo, Anson Mount, Ethan Peck and Michelle Yeoh.
