In Tuesday's episode, Anna and Dolores realised that a locum doctor at the medical centre blundered Carol's test results - allowing the cancer time to grow.
Thursday's drama begins as Anna tells Dolores: "I'm heading over to Carol's now. Have you still not spoken to her?"
"I'll wait a bit," Dolores replies.
"I really don't think you should delay any longer, Dolores," says Anna.
Later, Dolores meets Joan who tells her: "As your legal counsel, I have to make you aware - if you do this now you could lose everything. Do you understand? Everything."
