We got our first teaser for the four Star Trek: Discovery “Short Trek” adventures last week, and today the first preview dedicated to a single mini-episode has premiered ahead of the October 4 debut of “Runaway.”

In this trailer (region-free on Instagram above, here on YouTube), we see Ensign Sylvia Tilly (Mary Wiseman) in the Discovery mess hall, where a quiet moment turns to calamity as an invisible creature is revealed, throwing the mess hall into chaos in the process.

As of this writing, we still have no word on when “Runaway” will be available for Discovery fans outside of the North America — but the first “Short Trek” will debut Thursday, October 4 at 9:30PM ET for CBS All Access subscribers in the United States.
