Anyone who understands Sadhana's character would know that she will
never let Alekh go into the fire, she would rather go herself. Another
point, Sadhana heard Alekh saying that how would he survive if something
happens to his mother. So she must have gone to save Vasu for her
Alekhji.
As for Ragini holding on to Ranveer, it was her natural reaction. She
does that in pretty much all the scenes. I think she does that for her own moral support than anything else.
Alekh couldn't free himself to save Vasu but when he will know that
Sadhana is inside, I am sure no one can stop her hero to save her. Does
it mean that his love for Sadhana is stronger than Vasu ? Cvs just have to
show Sadhana saving Vasu and Alekh saving Sadhana. It seems end result matters the most to them than a proper script.
RagVir part,so agree!Even we saw her holding on to his collar during that kulfi scene.
