It was such an interesting contrast between devta conversation and shiv conversation about the same thing. While shiva started to open up and told raavi such a huge secret that could make all the family more upset and guilty devta tried to handle the current issue in a more practical way but it did lack more emotional depth unlike the shivi one. Though I think there is a reason shiva told raavi the family planning secret of gaura now if they use this to further the dreaded baby track this might be a reason raavi is the only one besides dev and shiva to know this secret.
