The possession story line will always be hilariously delightful.
Marlena goes to Louisiana in search of John but is captured by a criminal mastermind, Stefano DiMera. He forces her to call her husband, Roman Brady, and tell him that she is with John Black. This is the final end to Roman and Marlena’s marriage. John and Marlena escape, but Stefano also returns to Salem. He begins giving Marlena mind-altering drugs. Marlena completely switches personalities, and it is soon revealed that she has been possessed by the devil. John Black, who was a priest at the time, is forced to perform an emergency exorcism
I kind of wish that I had the patience to find the episodes and watch the full storyline but until then, YouTube clips will have to suffice. 😀
