I observed that one of my crewmates was committing suspicious actions such as utilizing the ventilation system to traverse around the spaceship in we were compelled to reside in for all of infinitude. As the specified crewmate was committing these suspicious actions, I understood that the crewmate in question was the imposter that was killing my crewmates. Accordingly, I traversed via foot into the cafeteria to press the emergency meeting button to summon my crewmates in order to vote out the suspicious crewmate that may be the imposter as he committed the suspicious task of utilizing the ventilation system to traverse around the spaceship.
