Falcon Crest (1981) : 3x3

After their baby's accident, Melissa and Lance agree to a truce, and Lance and Angela are soon thrilled when Melissa announces she's pregnant. Carrying out Angela's plan, Dr. Lantry informs Maggie and Michael that the bullet in Chase's spine has caused an infection, and that he may have to operate. Later, Lantry discreetly injects drugs into Chase's I.V. During this, Richard becomes guilt-ridden when he learns from Philip that Jacqueline was dying of cancer and stepped in front of Richard to spare her son from the gunfire. Richard and Melissa then plan to gain Julia's trust to manipultate her to avenge the deaths of their parents. Meanwhile, Maggie begs Michael to face his fears and take over Chase's case. That night, Dr. Lantry triumphantly announces to Angela that Chase has a raging fever and could die whenever she wants. Angela is horrified, but Lantry coolly informs her that it's too late and reminds her she's an accomplice to murder.
