I guess that’s one last item they have for EpIX - the whole helmet thing. Was it speaking literally or was it more like a dark side vision when he touched it?
I’m not sure what you mean by “the one last thing.” It’d be interesting if they go back to it but I don’t think Kylo was literally talking to it. More like a totem that helped him center himself in the dark side (like speaking to god by praying to a cross).
