even i think it is shesha...coz shivanya has seen numerous times and knows very well..how ritik has faith in her and will support her ..this scene would make sense only if it is shesha and she sees ritik ka blind faith in shuv...shesha is being made aware of the depth of feelings ritik has for shiv..now the consequence of which only cvs knows is what...
also shiv entering the house back has to be some major thing i suppose...there was an article that everyone in the house are surprised at shiv's changed behaviour and only shailesh thinks she is the naaghin so maybe they keep an eye on her and his wife sees her changing...
thanks for the video...it is so complicated for shivanya right now and aww ritik just have this faith in her always
