Mangala Gowri Madve: Soundarya manipulates the family members

Recently in the show Mangala Gowri Madve, Soundarya apologises to Mangala for all her misdeeds and pleads to give the antidote. Mangala agrees to her request but puts forth a condition to accept all her crimes before Rajeev.
Soundarya arrives at the police station, apologises to Rajeev, and confesses all her misdeeds, which shocks Rajeev. After confessing her crimes, Soundarya rushes to Mangala and pleads for the antidote.
However, Mangala makes a shocking revelation and informs Soundarya that she did not poison her. Soundarya is devastated and tries to lash out at Mangala but fails.
On the other hand, shocked by Soundarya's confession, Rajeev returns home immediately and reveals to Karna and Anusuya about Soundarya misdeeds. He also confronts them about Soundarya's intentions. Realising that they are hiding something important from him, he demands them to reveal the truth.
As Karna decides to come clean to Rajeev, Soundarya enters the house and confesses that she tried to kill all the family members and pleads Rajeev to arrest her. Shocked by her strange behaviour, Rajeev confronts Balli and she reveals that Soundarya might have been mentally affected due to the tough rituals that she performed.
Later, delighted that her plans to manipulate Rajeev and the family worked, Soundarya and Balli celebrate with joy. Confident about the family's blind trust in her intentions, Soundarya soon reveals that she will make the most of her act of insanity and launch a final and deadly attack on Mangala
