Still a big loophole left!

Arjun asked vasuki how did atika go against mankind and become subservient to takshak despite the kind of person he was before, vasuki didn't even give a proper reason as to what takshak did to convince astika to get on his side and how he made him so ruthless. Such a big gap in the story-writing that it gives zero depth to the story. He practically just repeated everything we all knew about astika rather than tell us how things came to be what they are between takshak and astika. Major fail!
