Since many of you have written about the spectacular treasure hunt scene in details and also about hero, heroines and all the villains and poor soldiers, I will jump into a fresh joining the Villains group. Yes I will try to speculate how Mirza Hakim may turn negative and go against Jalal.
Form whatever we saw yesterday, he is still positive and curious about this Maa, Beti, I mean Chand Begum and Nigar. So far he had not heard of these people and all of a sudden the news came a hot potato that There was one more wife to his father and she had given birth to a girl who is even elder than Jalal. The news of this new entry to the family is not the only shocking news to him but also that the Begum of Human had been kept captive for years together in Agra and she had been last spotted was near the palace. What an irony to the twist. And added to that, Todarmal update him that such things can happen, only if a person with a higher altitude is involved in that. So the bench is set to doubt the senior level person at Agra palace for this kidnap and wrong custody of a queen.
Just think it over with normal logic forgetting about Maham's involvement in this as she was loyal Minister of Sultanate and otherwise a mere Baandi. So no one will doubt her in their normal wisdom unless they get some crucial doubts. So there is no chance for Mirza to doubt on Maham. More over he can't suspect his mother's involvement with Nigar and in this war as Kabul army has not come to fight the war but it was from Haider. So all he can think along with others in Agra that Nigar has join hands with Haider and waged war on Agra. Mirza is not even aware of his mother's remarriage, so he will not suspect her to revolt against Agra. If what in think happens, even Abul Mali may not fight war directly but will stay in the back ground. Only on victory will he come out and acquire the sultanate either for him or for Mahachuchak. Right now this will be a war between Jalal & Nigar alone. So that is the reason, why Jalal is reluctant to fight this war.
So Mirza Hakim along with his SILs will go to war field and combat. For all probability, Nigar might escape from the war field when they were in the verge of losing.
Coming Chand Begum, we can expect Maham to keep her captive in a secret room inside the palace and nearer to Hamida's quarter. She may use the secret trap door Jalal had shown Jodha once and Jodha & Salima used the other day when Jodha Soiled Benazir's attempt to kill Jalal. So even if someone find Chand Begum on a later date, no one will doubt Maham, and she would have already hatched a plan to join hands with Mahachuchak bargaining for Delhi while she will help her with Chand Begum & Nigar.
When the war is concluded, Jodha along with other Begums, for some reason might enter the palace through that entry or Maham may allow Chand Begum to escape from that secret door and scream aloud or make someone scream "Chand Begum, Ruquiye, kahathe aap etc." and later will hatch a story that Hamida had kept her captive so that her son need not have to share his power and land. (By then she would have brain washed CB on lying if she wants her daughter alive.). This could be the precise reason why they showed MCs Flashback on discussing Nigar's right to Delhi Taqth.
With all this background, Mahachuchak will peptalk Mirza on how is it possible to have a Begum imprisoned without the knowledge of Marrium Makkani or Shehenshah. Since Nigar come in front of them in public, they had to bring out Chand Begum but if Jalal had any intentions to share his power, why he would have allowed his army to fight Nigar? Or like since he didn't want to get blamed for killing his own sister for power, he allowed his wives and brother to fight against her. If he loved his brother so much, then he would not have allowed him to fight his own sister while he sat back. All these are only to show the world while internally he doesn't want to part with his power. Maham might even tell him a cooked up story that since she came to know about this, all her powers have been taken back and she had been branded as a gaddari. And she had been threatened of death, not only hers but also Chand Begums & Nigar's. So she had to keep quite. Now that she knows MC can take care of Nigar & CB, she is ready to testify on this issue etc,.
However, MC may not allow MH to wage war directly but might advise him to stay put in Agra and collect all the necessary details on the power, money etc. And also build his own army under the nose of Jalal so that when the time ripe, he can revolt.
