Spoiler tagged so any resultant discussion can include episode content - not because I consider my theory a spoiler. Could it be that the Klingons we've seen so far ARE some of the Augment Virus Klingons? Their enthusiastic chant of "Remain Klingon" seems a little odd if they're already fully Klingon - I get the idea that they feel like their culture is threatened, but even so. And giving Klingons plastic surgery to compensate for the effects of the virus was mentioned in the episode of Enterprise. Maybe that's exactly what happened - and they went overboard in compensation. So these Klingons are the Klingon equivalent of the overdone Barbie doll plastic surgery women of 20th/21st century Earth? More Klingon than Klingon. Which would explain how the showrunners plan to have both TOS and TNG style Klingons running around in the show, too. Maybe Ash Tyler is Voq - but turning him into Tyler involved less alteration and more DE-alteration?
