Logic gayi tel lene.

So i've been thinking about the episodes and one thing has really been confusing me. From the beginning of the show we've always been told that the Taneja's are rich. I mean the first dialogues were a woman saying her sons life would be set if he married Leela Taneja's daughter. We were also told how the Sarna's were one of the most influential families. Now, after finding out that Kunj has this disease, they need blood and the only person who can provide it is Yuvi. Because of this they let him free? Are they crazy? YOU are two of the richest families in Amritsar, why don't you contact international blood banks? why don't you ask in other hospitals in INDIA! They just thought that "hey no one has it in our blood bank in Amritsar, so no one else must have this blood type, it must be very rare" Clearly if someone you know has the same disease it's not that rare guys COME ON!

They have to fit in Yuvi by hook or by crook. So bye bye logic

Well if they got blood from somebody else then yuvi wouldn't fit in the story.
To include the villain, cvs bid adieu to logic
