At this point I am convinced that we have to watch epis r stand alone... Every other thing is brushed off apart from the wrong things done by Ar and Ab... So yeah for the time being Ru is a true sister of Ab
You cannot forget her next line......if Ar is right for supporting hos mother then so you are for supporting your brother.
And also something about how society praise men for being achha beta when they support their family but not women who do same.....
Achhi sachhi mature indeed.
