He lifts the spiked border with his body
He leaps and jumps to make sure she has that taveez back on
He puts his hand on top of hers to protect her from pain
How much does he know Ravish? Not much at all. He knows he is his brother & he would've gone all out to save his brother even if it's out of humanity. All he knows & feels is that he cannot leave Vividha by herself.
Vividha and Atharv's second, if not first instinct is to protect each other regardless of any misunderstandings.
So when Atharv asks Vividha if she trusts him...we know why she does more than she trusts anyone else. What Vividha wants, Atharv gets. If he says he will ensure Ravish's safety, he WILL make sure he is safe. Those subtle nuances where you could feel his hurt broke me a little. It's not jealousy, it's his biggest insecurity being fed and seeing things from a perspective Vividha isn't even thinking of but hey ho...when has love been smooth?
Atharv once said what Vividha wants, will happen.
Actually he said it as baby Atharv too...he said I'll get you whatever you want.
