This happened to me too i was playing and was the imposter pulled off a double kill and when the body got reported the person said that it was me when asked why the person that they are on discord and their friend told them
The other person that was alive said that let's vote out pink(i think that was the colour) and we did
I would lock the doors to cafe, then I would sabotage O2 so the person goes there and uses the nearest exit, (which is by weapons) then I would wait and see who goes to the cafe and who it gonna start an emergency meeting.
