Today Atharv being in the condition he is, still has that ability to have an easy going conversation and connection with Vividha. Whilst she's so readily accepted how he is and already talks to him with a certain ease. It's like they never were apart! Their circumstances have changed and how but their compatibility remains the same. Isn't it beautiful? Their understanding of each others emotions is the most natural thing to them.
As Vividha reinstated once again, you could physically tear them apart but by soul, mind & heart they're always together, always in sync.
