Brother Jon finishes his prayers and looks up to see you all assembled around him (Aquarius I'm assuming is with you).
He looks sombre, "It is prepared." He begins, "You will have four questions, remember to be precise, he won't really have come back, only the knowledge that his body retained in life, it will have no initiative to respond on it's own."
"I can guarantee you four questions, but beyond that I can't promise anything. I suggest you decide now what you wish to ask, and the exact phrasing."
