REHAAN HATES LIES ONLY WHEN IT EFFECTS HIM, NOT OTHERS.

why he is still talking and seeing his mother and not informing aahil?so rehaan has no right to blame seher or talk about hating liers bullshit. aahil doesn't deserve any of this. in my opinion tanveer is a criminal and whoever covers her is a criminal too. seher is not going to forgive him and his mother when she finds the whole truth. even though rehaan has no idea that his mother killed entire khan family. but he knew that his mother killed few people to get the property. remember in the graveyard she told rehaan? seher, sanam, and aahil will never trust him. but i am not trying to cover seher either, whatever she is doing unbelievable. so we don't know sehaan will end up together or not. as long as saahil are together,i don't care who ends up with rehaan or seher.

she never ever told him abt murdering nawab
it was only billi's flashbacks to let the audience know abt how the nawab was killed

I think Rehan knows she has caused some bloodshed... because Rehan himself returned the shawl of Nawab that she gave saying that it was' Khoon mein doobi hui"...
