i think was ridz did was really brave like armaan said in a way she did it cuz she wanted to repay the debt of the gupta family cuz she was adopted. I think she might of done it even though she wasnt adopted as its ridz kind nature but i think there could also be a chance of her not doin it also. but who knows anyways my question to u is would any of u take the blame for ur sis?? i personally dont think i would do that as people learn from the mistakes n hidin or coverin others mistakes always worsen things..ridz did wrong as anjali almost killed someone ya she regrets but maybe the lack of knowledge or prep she is the one who needs to give her exams again but ya i wouldnt do it for my sis i tell my sis to have enough guts to admit her mistake and face the problem head on. takin the blame would do nothing..so ya love to hear ur views!
cheers
