In og the wedding bet the leads was forceful as almost sindoor dhan was left otherwise both were married as they took the phere as well. Later he refused to accept her and even marry her. However she was okay to marry to him. Even she didn't took any stand...
Here in sikh wedding, phere or lavan is important and before lavan the cloth or ghat bandhan is done by father is actually kanyadhan. So Here makers did a good job by making Sahiba Reject this wedding so that Angad in whim will not only accept her but will take her as a punishment for seerat running away and decieving the family.
Plus here media is outside and the guests are going too, so before anything goes viral Angad will marry her and she has to marry ... and here wedding will happen with all members ... I have a feeling we might not get storeroom seq ... Because here manbeer is there too.
