We’ve got yet another roundup of Star Trek: Discovery news to round out your Wednesday evening — from one more promo video for the upcoming series to reactions from the cast on social media.

First up tonight is a new Discovery promo released online today, which is mostly previously-released footage, but gives a good close-up to Chris Obi’s character T’Kuvma, angrily spitting the phrase “We come in peace!” to camera — likely aimed at Captain Georgiou and the USS Shenzhou crew.

This close-up gives us a great look at the false Klingon teeth worn by the actors, which Obi showed off once more in a humorous Twitter video this afternoon:

David Mack’s Desperate Hours, the first tie-in novel to the upcoming series, is due out in stores on September 25 — and the author took to Twitter this week to warn readers that if the book appears in stores ahead of the planned release date, which occasionally happens, the novel will contain spoilers for the September 24 premiere.

If you get your hands on a copy of the book early… keep those spoilers to yourself, fans!

Discovery actor Sam Vartholomeos — who we talked with at the Las Vegas Trek convention — is taking college courses in New York City this fall, and shared a view from one of his classes… where a professor showed off the Comic-Con Discovery trailer to his class without knowing Sam is featured in the video!

Hopefully Sam will have some new Star Trek insight to teach his professor!
