But Natsu, Lucy, Wendy and Juvia are still out could, so it's unlikely that the poison disappeared together with Torafusa. So someone has to save them.

I doubt Porlyuscia has the fitting antidote for a Demon poison with her or that she's able to make one quickly enough to save them from this 5 minute death-sentence, which would only leave Wendy or Chelia with the ability to save them in time. And of them Wendy is already en-route.
