So recently I learned how to use admin table. If, say, there is two people in a room on admin table, and one blinks and quickly comes back, that means a kill happened there. Say it happened in electrical and one of the players disappeared into med bay. Check who runs out of med bay, you know the impostor. Epic admin table 😎

Also watch out for venting. Say there is 4 people alive and two people are in Weapons, one is in security. The one in security disappears and quickly somebody goes into electrical. Can't be the two people in weapons, so that guy is impostor.
