I have a super dumb theory but it still can happen!
What if this Palash guy is set up by Dewa to irritate and harass Tara??
If Palash comes into the picture, Tara will feel unsafe and may be using this Dewa would marry Tara.
After marriage, he can have ample opportunities to torture Tara.
Maybe the fight scenes between Dewa and Palash are to fool us??
Or maybe the makers are playing with our minds to create suspense.
Or we are fools to think Dewa is so gullible as to forget about his revenge so soon?
Anyways, Dewa has a strong reason to take revenge - because for whatever reason Tara has thrown Deva to wolves and made him suffer hell.
Let's see what happens.
