check what five suspects woman (Rosalind, Elaisha, Rosetta, Lila and Argasta) ask about one another - there should be a hint if someone acts diffrent or strange.
I've made so it is always random who is an imposter.
Sorry, but I've been trying for two hours, and the conversation between these five people is the same every time it loads, and there is no difference, I don't know if the bug is triggered
