Symbolisms
1)Chain tying scene
So tying the chain shows love and commitment to the certain relationship. So Veer doing it shows his commitment and love towards his wife . Truly he asked her to keep his love safe and carefully.
This symbolizes a new beginning in their relationship too like it did for Ramadheer and his wife.
I think it also demonstrated that somewhere he is slowly taking over her parents place (in a good way, not like getting rid of her parents). Because when Veer did that, she started crying and Veer knew it was because of him, not the necklace. It came back to the jail conversation and then Rani said if he goes to jail, it will cause her pain.
This is the second time we saw Veer doing something with Ramadheer's things. First was him tying Ramadheer's dhoti and now it is him making Rani wear the same necklace that Ramadheer gifted his wife.
2)Hand slipping scene.
It shows Veer doesn't like to leave Rani now but he is leaving just because to save Rani Sa.
3) Cleaning the jewelries
she might clean the blame and save the name of Rajawats the similar way.
4)Rani searching the baking soda everywhere but found at her closet.
It symbolizes that she finds the culprit everywhere when she is right in front of her. while she is searching for it due to distraction of Veer she fell. So even in searching for the real culprit due to Veer's distraction she will fall but he will save and ultimately lead her to real culprit. We saw it once as he subconsciously said she .
