Agent of Chaos

Green told us that Orange only killed Lime, so I'm gonna assume that Green killed everyone else. I do find it most likely to be true, Green's manipulation and acting abilities are good.

1. WHITE (I had this wrong at first, sorry!!!)

I initially thought Green kills White during the storage scene in ep.1, but Green and Orange were actually replaced/infected (depends on how you see it) by the imposters during the storage scene!

Thank you to @shimohyo for pointing out to me that you can see Green and Orange sliding into the same direction of the alien :)

White is instead killed between the storage scene and the pizza party.

Maybe when everyone else was working on setting up the party in cafeteria, White was alone because they don't tend to do any work. It's also plausible White was simply exploring the ship, or was pulled away by Green.

2. BLUE

This hallway is right outside of security, so Green would be able to see when Purple has exited the cameras so Green can kill Blue unseen.

I'm unsure if Green would have used the reactor vent or the security vent. Ingame, Green would have to use the electrical or security vent to get to medbay, so Green could've walked into security after Purple and used the vent in there.

but Lime literally vents from cafeteria to reactor in the intro so it could just be that all the vents are all connected to each other in this version

3. LIME

okay. we all saw the kill. Lime obviously randomly exploded for no reason.

Ok but actually Black and Cyan went to have emotions, leaving Orange alone to find Lime.

BUT! I will say that Green didn't kill Lime because Red had just left Green in reactor!!! If a body turned up in reactor and Green was the last person seen in there, that'd be suspicious.

also take this caption typo

4. CYAN

Green slipped through the suspicious newly placed vent during Purple's backstory stuff, leaving their crewmate body behind. Green took the vent to electricity, killed Yellow, then slipped back to o2.

5. YELLOW

evidence likely planted by Green during this sequence NEXTTT

6. BROWN

hey Green you're looking suspiciously saggy over there. Almost like an empty costume.

anyways I think Green exited their crewmate body, used the cafeteria vent nearby to vent to the Kitchen, then killed Brown.

7. Black

Everyone was separated, letting Green kill Black alone.
