Star Trek: Discovery Season 1 Episode 15 The final minutes PICTORIAL Video

As you will note if you have seen the episodes there is one obvious bit missing from the pictures. CBS may yet release pictures of this but not quite yet. However you don’t have to look far on the internet to see what was revealed at the very end of the episode.
Star Trek: Discovery Season 2 is expected to be available some point in 2019. Maybe we just have a year to wait?
