I liked the episode.
All the characters came one full circle and no bad vibes between them all which is good..
MISHTI's actions are justifiable now . All she wanted was a family for Ruhaan and her sister getting her love.. I don't think anything wrong in that.
For people who felt that she should have revealed about the disease to her family , I think she did the right thing by hiding it. If her disease was known to all then no one would be happy and crying buckets, which would be even difficult for a dying patient..
So all in all good end to the show according to me..
Now eagerly waiting for the epilogues..
