Actually, yeah I do think that the scene might've symbolised future tracks about Navya but about Rama taking AnYa to an extreme step, I don't think that's what she wants. She wants Anant for Shagun, so I don't think she'd like Anant getting any closer to Navya than he already is. I just think she wants Anant and Navya exposed so that the ego of the Bajpai's is shaken and they themselves ask for Shagun as their daughter-in-law.
I think this whole concept of pre-maritial sex has been shown too many times on Indian Television but Navya is a show that has taken real issues and dealt with them in a dramatic and narrative style but realistically. Of course, pre-maritial sex is a real issue but it does not always as bad consequences as they have exaggerated in the past on Indian tv.
In this case, the idea is to separate Anant and Navya by humiliating them in front of their families. Sure, the pre-maritial sex could work but it's a bit too cliched, and I guess as viewers of Navya we are used to surprises in the storyline, so it would be really disappointing if the creatives decide to opt for this storyline.
