I think if Renu and Meeta do find out about Anant, they shouldn't be quick to judge, he should at least be given a chance to show to them just how much he loves Navya and tat he'll never hurt her. Navya should also stand by Anant's side if she trully has faith in him, otherwise their relationship won't go anywhere- I mean in a relationship, both partners should be equal and work together to overcome any problems... So when the confrontation happens, Navya shouldn't shy away from the relationship she's tried so hard to keep a secret. Obviously Anant is important to her, so she needs to show that in her actions.
