This is the episode in which Daniel Reese (Rock Hudson ) finally professes his long unrequited love for Krystle Carrington (Linda Evans ) and they share a passionate kiss. When it was later revealed that Hudson was dying of AIDS, tabloid newspapers erroneously (and ignorantly) implied that Evans may have contracted AIDS herself from such contact.
Technically, the "Kiss Episode" between a dying Rock Hudson and Linda Evans took place in two episodes, beginning in the former, The Ball, and continuing, liberally from the scene pausing at the end, here with the end of the continued kiss and then another quick kiss.
Interesting to wonder how the mystery photographer cataloging Krystle's intimate moments with Daniel Reece is able to get such good shots without peering through the lens.
