I just recalled some of the sections where suman and shiva are involved.
1. Gaumbi second marriage - he was a kid, he scared that man but did not say much to suman.
2. Suman going to ashram - She was repeatedly taunting dhara, shiva again just said " Maa, gaadi aa gayi hai chal na"
3. Danda kaand - Again he was in tears asking suman to not oust dhara. Taking the blame of everything and saying what dhara did was right.
4. Savan puja - Suman has said terrible things to dhara regarding her pregnancy. Shiva said we will go for kanwar yatra, shant hoja. Thats it.
Tbh for an ample amount of time I believed shiva is butchered for this chewing gum track. But actually no, he is just behaving like himself. He is rowdy baby in front of everyone but Suman.
Also he is very civil in case of girls. When he did not even considered rishita as bhabhi, ( haweli days) all he did was to rant in washroom saying rishita is like kutte ki doom.
If writers are keeping this points then I am damn sure, wo din durr ni jab shivu baby dobi raavi k liye bagawat karega. 🥳
