Remember when Demir told Sadakat Alya will be the one to bring down the Albora. She was shaken by what he said because she could already see the influence Alya has on Cihan. She's been out of control since then. Sadakat sees Alya as a threat to the influence she has over Cihan. She can't control Cihan if his wife has more influence over him than her. Sadakat's biggest mistake is allowing the past to fuel her ambitions. She's the destroyer. Not Alya.
