Showing up from gosh knows where as a witness for the prosecution during Blake's murder trial (he is of course cleared despite her), Alexis then sets about to get even with Blake for leaving her, and to undermine the influence of Blake's new spouse, Krystle (Linda Evans). Spitefully wedding Blake's business rival Cecil Colby (Lloyd Bochner), Alexis suddenly acquires the financial wherewithal to put her wicked schemes in motion when Cecil drops dead of a heart attack. Also introduced in season two is Dr. Nick Toscanni (James Farentino), the psychiatrist for Claudia Blaisdel (Pamela Bellwood), the mentally unbalanced mistress of Blake's bisexual son, Steven (Al Corley). No sooner has Dr. Toscanni joined the cast than he is seduced and bedded by Blake's predatory daughter, Fallon (Pamela Sue Martin), who is still the in-name-only wife of Cecil Colby's son Jeff (John James). Also making her first appearance this season is Krystle's avaricious niece Sammy Jo Dean (Heather Locklear), who goes on to marry Steven and bear him a child named Danny. When Alexis pays off Sammy to walk out on Steven, he weds the widowed Claudia on the rebound. By season's end, Steven had vanished into the wilds of Indonesia -- and soon word reaches the Carrington mansion that the family's "black sheep" has been killed in a horrible accident (wanna bet?).
