Nora's concern for Carol grows in Sunday's Fair City on RTÉ One and the RTÉ Player.
Carol is keeping her cancer treatment a secret.
In the teaser for Sunday's episode, Nora says to Carol: "He wants to come back."
"He can't come back," Carol replies.
"What does that mean?" asks the upset Nora.
"I don't see a future!" shouts Carol.
