I had so much fun watching this episode,and i really like the new science uniforms,and even that post-credits scene was awesome,and i like cinematic dark tone of the scenes with the two ships.However ,this kind of problem has one easy way to be resolved : they should leave the ship temporarly and then they should reduce the air level to zero ,and all the tribbles would die.This was a trully Star Trek episode ,better than all the episodes from the main Discovery series .
