Aradhya and Pradyumma Rao...
In Aaru's mind knowing that PVR wasn't the person who did shot Tulsi hence making him an innocent in this crime. He should not be punish for a crime he didn't do since that not the way justice usually work anyway. He should be punish for the wrongdoings he had committed in the past and I believe when Aryan will throw him out of the mansion - that is the best punishment he can give to PVR. Since power, wealth and blood are three things that mattered to PVR the most and now due to aryan he will lose his power and wealth this will lead him feeling devastation and he will have to be force to learn how to live in his life as an ordinary common man not a powerful and wealthy one. Due to PVR's impulsive actions aryan had made his entire family to suffer alongside with him as a consequences for his action with the intend of killing him and think that he ended up shooting his mother.
Many may disagree with me on that and this is fine too but I don't think PvR is actually capable of shooting since he had use that method in the past to pinpoint gun on people making them feel the terror and then are forced to obey him. It's was PVR's way of keeping people within his control including members in his own house but doesn't actually commit the deed. When Tulsi died - PVR was shocked, scared and confused - he didn't look like he was happy at all. His reaction was the opposite of the real killers Jairaj and Purva. They looked happy show no remorse and were just worried about covering their tracks. Pvr look weak and even though he said to Shashwat that if he had shot Tuksi he would have proudly admitted it but I don't believe him at all - he was just putting a mask on and his body language and state of mind had proven that. He was a bad man but not a killer. He didn't have that in him.
Now coming back to Aaru supporting PVR, let analysis this:
He had planned to kill her once but when Kumu had revealed the truth - he stopped there and unwillingly but allowed Aaru to remain with him and their family. Despite Kumu saying PvR will kick Pav and her daughters out when he find out she had given birth to another daughter and that didn't happen at all. They have been living together as in one house. He had shown some goodness in him by allowing Aaru to stay and that had given Aaru and her parents a hope. Aryan had at time had witnessed PVR wanting to kill Aaru too but still love and believe in PVR even at that moment. For Aryan, PVR and his Pavitra aayi were the two people he had loved and bonded the most in the family he was nutured before the truth was out. Like Aaru, Aryan too didn't believe PvR was a bad man even after witnessing in his own eyes that pvr had attempted to kill his wife. Aryan love PVR and wanted to be remain in his side despite kumu telling him differently. Perhaps Aryan like Aaru at the time believe that PvR didn't actually pull the trigger made a difference and thus he believe PVR still a good man...
When PVR went to the factory with the intention of shooting aryan - Aaru had managed to talk him down and even offered herself to be shot if that lessen his anger which he didn't do. He never shot her and was about to leave aryan alone. For Aaru, she saw a hope and goodness in him, she saw what type of man he could become. She understood what aryan had always saw in him. Aaru had talked to him to reunite him with aryan as she knew her husband at the time love PvR more than life like she love her aayi tulsi...of course PvR came back to shoot aryan but this time in anger since Kumu had attempted to injured his son Shashwat. Whether he would actually pull the trigger or not is debatable. But it probably wouldn't happen since there no bullets so he is innocent in either way. At that day he couldn't have shot aryan or tulsi. His anger got the best of him and thus he was there wanting to hurt aryan.
Aaru couldn't let go that he had shown goodness in him the first time when she took him away and cling onto that hope and, knowing that aryan love her grandfather more than life even though he won't admit that anymore, she is on a mission to reunite a grandfather and grandson. She even tried to explain that to aryan in the court scene when she was on a stand. Aaru was being a good wife by trying to reunite him with his nutured family and I will admit that it's wasn't the best or right way of doing it so but her intentions were honourale. And like aryan once upon a time Aaru too still believe PVR is a good man just hard faced. I have noticed that PvR had that effect in his grandchildren, they can't help but either love or hate him and end up coming back to him. 😆 And aryan will too eventually. 😆 PVR is complicated man many feared him, or admired him but his family love him and couldn't let go of that complicated love they have for him.
Aaru is no different from aryan, in the past he supported his grandfather when Aaru didn't and believed he was wicked man, now aryan believe he is a murderer and Aaru believe he can be good and is innocent in this Tulsi's murder crime. Like I said its KD season 2 where the roles have been reversed! 😆 😆
