(In this chat, you replace red when he encounters fortgreen, good luck :D!)

You had been a crew your whole life until that day when Purple and Pink attacked you. Blue, White, Yellow, and Glitchy were escaping until you had to fight for your life against Purple When he was about to attack you with his knife, you put the imposter device on to block the attack, but it was a big mistake; the device broke, releasing the imposter parasite and turning you into one In the end you managed to get rid of him and enter the escape pod, thus going to Polus without saying anything to your team.

(time jump to when you find Fortgreen in the storage)

You were going to the storage You were doing a task when suddenly an imposter emerged from the corner hole, whose existence you were unaware of, and tried to attack you, but you defended yourself, showing that you were also an imposter, He was surprised at first, but he told you that "supposedly" he had also been a crew member, but that a parasite trapped him in some "supposed" mines and that he ended up becoming a shapeshifter

(What will you do now with this information?)
