"Matt H, the snow interrupted MEDIUM last night & we have no idea how it ended. Please help.
MEDIUM SPOILER!
We lost our connection just as Joe was talking to Kelly Preston, for the second time, in the restaurant. Did he tell her he would not accept her terms? What else happened? What did the killer really look like & who was the guy in her dreams?"
At the restaurant Joe told Kelly that he couldn't accept her 51-49 percent breakdown of ownership. We found out at the end of the show, however, that he changed his mind and decided to take it, so the two of them are now in business together.
As for the murder, the man Allison saw in her dream really was the killer of the FBI agent and the other murders. The FBI agent's ghost lied to Allison so he could maneuver the killer into getting his comeuppance without the possibility of getting away or getting off on a technicality during a trial. The killer was killed in the car crash that Allison also dreamed about (though we never saw the driver of the car that ran into the young couple in her dream.)
Hope this helps.
