Here just my POV regarding Arhi. I don't know why I see differently. If you go quality versus quantity, Anji did get a large part of the screen space these last episodes, but Arhi bonding seems to be at it's peak right now. K is still at the center of the stage. The way she stole his heart at the Mehndi sequence was beautifully captured. She stirred his emotions in and out, he impulsively approached her and melted on the dance floor as if the rest of the world had stopped existing.
The ending hug at the hospital was one of the most intense Arhi moments. A withdrew himself from the rest of the family. Nobody consoled him, because they know they can't. Only K could and he submerged himself completely in her embrace. He let all his emotions out that had been bottled up for so long. A was a free man today. Such is the power of K. This embrace spoke volumes about K's support, their trust, love and strengthening bond. Not commenting on epi as a whole, plots or coming up MUs, TRPs or entertainment value.
