Credit to Fourierspace on Star Trek Reddit for catching this. There are costumes behind the woman talking which look alien but NOT Klingon. The speculation is that they are possibly a new Romulan design? There's a distinctive symbol of a winged figure on both of them. The other possibility is that they are MU Vulcan costumes, and the symbol could be the Rebel's insignia I suppose. What do you think?
