Major Medium spoiler alert:

The CBS drama will kill off its main character in May, as the series is casting for hospital doctors, nurses and orderlies to try (and fail) to save the life of Allison Dubois (Patricia Arquette) on the show's season finale.

But does this mean it will be a series finale?

It's hard to say.

The show is titled "Medium," after all, as it deals with the after-life and often focuses on various nightmares and fantasy scenarios. Because this May episode will be called “It's A Wonderful Death," many believe the demise of Allison will simply fall into one of these categories.

The installment will also feature the wedding of Scanlon and Lynn DiVovi. But will Allison be alive to attend it? And do you even want this show to return for another season?

Sound off now!
