Yes,Appu is lethal.She had been raised like that even if she herself is not aware about it.
But to be honest,I did not feel bad for that man.Not a bit.He tried to misbehave with her.That girl did not have any means to defend herself.It just crossed my mind that Appu's powers would have a been a great method of defence for all the women against rapists and eve teasers if she could control them and direct them according to her own will.Seriously,I felt bad for that little rabbit.But not for that guy.I think Kalpana knows how deadly her daughter.For Kalpana herself has turned Appu into a vishkanya to use her against the Mortals.I feel bad for Appu.She got the Destiny of a vishkanya which stands as a barrier between her and the rest of the world.Between her and Malay.😭And for the precap,Malay's chachi is too much😡
