Star Trek: Discovery Season 2 is well underway with Episode 3 releasing Thursday. The second effort has focused a lot around Michael (Sonequa Martin-Green) and her history with her adopted brother, Spock (Ethan Peck), but we have yet to see the iconic Vulcan onscreen.

When the producers and cast at the Television Critics Association winter press tour were asked if they could reveal when Spock would finally appear in the season, showrunner Alex Kurtzman had a short answer: "No." However, he and executive producer Heather Kadin explained why they've drawn out bringing Spock into the show.

"You've already seen photos because we've already gotten a lot of questions about the facial hair and what's up with that," Kadin said. "What's great and what Ethan is bringing to it to make it to his own and what we brought to the story, when you see him, it's going to be different from what you would have expected coming into the show."

Kurtzman added that the mystery surrounding Spock is to help emphasize how large his impact on Michael has been and to make sure the audience is fully engaged when the estranged siblings finally reunite.

"Spock is also a looming specter that has loomed over Michael and had so much to do with her defining her identity. We felt there was something really interesting in his presence being so loud in its absence," Kurtzman said. "We wanted to take the time to raise the question in an interesting way so that when Spock finally does show up, your appetite has been whetted but there are so many other stories that lead to his introduction into the show. Hopefully, you'll be invested in all of the mystery."

So they're torturing us on purpose, but it should be worth it. Good to know.

Star Trek: Discovery is currently airing Season 2 on CBS All Access.
