Jaskirat's life was a tragedy yet so many people (especially fellow spys in Pakistan) genuinely loved him and he was very lucky to have them (especially Alam, yalina and Jameel)
Okay so Jaskirat was brutally ripped apart from his original family and didn't even properly get to mourn the deaths of his dad and one of his sisters. He had no other option but to accept the role of a spy for pension and a way out of capital punishment. But where he really lucked out was the people he met in Pakistan (not talking about Gang members).
His journey started with Alam and Alam gave up his life to save Jaskirat. There was not a single ounce of selfishness in Alam. He truly adored both Jaskirat and his country India to happily give up his life. Even Rizwan was emotional at the end showing his attachment to Jaskirat.
Jameel too was a spy and Hamza kind of was so extra when he threatened Jameel to release Rehman in part one. I feel Jameel might have intelligence about Rehman supplying arms to ISI for Mumbai attack and that is why he conspired with SP Aslam to get rid of Rehman. Add to this, Jameel knows very well that Hamza is using his daughter for political backup. Jameel was kind of upset about this and calls out the age gap but then he immediately forgets at and supports Hamza without any backstabbing after Hamza officially becomes his Damad. In the climax of Dhurandhar 2, Jameel got emotional when Jaskirat leaves and I feel when he addresses Jaskirat as Baccha in the car he really meant it.
When it comes to Yalina- no comments. The cutie is a blessing. She is Laakhon farishton ki hai tu jaan
.She gave Hamza her 200%. She happily lived in the Khabatoor Ka Khana for him and supported him even after finding out he is an Indian spy. She also made him a father and gave him a family in an enemy country like Pakistan. Her call to Jameel at the end literally saved his life.
Special shout out to Ajith Sanyal too- he truly cared about Jaskirat and Jaskirat was more than just an asset to Sanyal Saab. He took immediate action and blackmailed the chief of ISI to safe Jaskirat and get him back to India. It was a refreshing change to see RAW members not fighting with each other and plotting against each other unlike other Bollywood movies. This movie had the best portrayal of RAW officers where they work as a team without any drama or ego.
So long story short and in summary- Jaskirat's life is a mess but he had so many people in his life even in Pakistan who really loved him and went above and beyond for him. I guess that is Jaskirat's biggest dukh- not getting to be his loved ones and always separating from them.
