At 10:28 it's obvious that Amanda is wearing a hairpiece, when Alexis ruffles her hair.

From this episode on, the only two actors to appear in every single episode up until the show's conclusion at the end of its ninth season are John Forsythe and Heather Locklear - that's a total of 75 episodes.
Not to be confused with the Season 5 episode of the same name.
This episode features a memorable exchange between Claudia and Krystle in which the former accuses the latter of being so passive about all the incidents going on the house - where brother is pitted against brother - that it makes her "the most dangerous Carrington of them all". This is actually the first time that Pamela Bellwood and Linda Evans shared a scene in Season 6 (Bellwood was off on maternity leave for most of the latter half of the season).
