Chris Deegan was the best in the sack.
Which is why he should have come back for Season 8, having been diagnosed with AIDS and dying before the end of the year. Steven -- because Chris dated Ted Dinard in the late-'70s before Chris introduced Ted to Steven -- becomes concerned that he himself may have contracted HIV from Ted... Adam gets wind of this and, Adam being Adam, immediately tells the family, setting of shock waves amongst the Carringtons. (Turns out that Steven is HIV negative).
Krystle's clairvoyant healing, initiated by all her head injuries, may or may not have healed Steven with a hug. We don't know for sure. She finds out about Deegan too late to fix him, but you'd think her newly-acquired psychic powers would have told her about all that in advance. But it apparently didn't. (She's new at it, after all).
All while the gubernatorial campaign is going on.
