Two songs were played in Bg during the episode.
Tera chehra jab nazar aye was the perfect song for showing the angst with Arijit crooning in his magical voice. The lyrics are so damn perfect. That song used perfectly shown in the movie Sanam Teri Kasam to show the passionate selfless love Inder had for Saru who was clueless and Oblivious towards possessive and protective Inder's feeling almost comparable to Shaurya's condition of one sided care and his exhaustion at being underestimated and thought of poorly by Anokhi.
The second song Maai teri chunar lehrai again by Arijit symbolizes a child's need for protection and hiding behind his mother's pallu. The song played in the movie ABCD 2 when Varun Dhawan's character had literally disappointed his mother by cheating. The song was a cry for comfort and guilt by a scared long child. This was the perfect fit for Shaurya's present condition too who was hiding in shame and guilt unable to face his mother and hug her and breakdown like he really wanted to. He was physically and mentally exhausted with sleepless nights, comforting Shaan and Anokhi, finding her, getting battered and bruised in the riot, doing a thankless job of saving somebody and seeing a couple of dead bodies. He needed some respite and comfort of a hug or putting his head down in her lap after a long traumatic day. But he couldn't do that. Jab jab mujhpe hai utha sawal maai teri chunar lehrai...the next scene we literally saw Shaurya being repraminded and misunderstood and his mother taking stand for him and protecting him from blame and accusations had my heart. The sense of shock or surprise on Shaurya's face seeing Astha standing up for him was a sense of wonderment. That song described his angst for his mother too.
