AVM n Sonu's relationship post revealing of truth

We all have been talking about Ahaan n Ishqi but it will also be interesting to note Ahaan the Mahan' s relationship with his sister. He may forgive her but what will be Sonu's reaction when she will come to know that her brother is madly in love with the girl from whom she separated him for six long months due to her own stupidity n selfishness. Moreover will Ahaan be able to forgive her totally for her behind duped n all?

I think Ahaan forgive Sonu after all she is his sister...he thought his family and friends never do wrong only Ishqi do everything

I mean why does ahaan have to forgive Sonu? Sonu was nearly raped and was traumatized. Ahaan was the one who failed as brother due to his misogyny and expectations from Sonu. To the point where she couldn't trust him to understand her with such big problem. Ahaan and Sonu share an extremely toxic relationship to be honest. It should be ahaan who feels guilty, that his sister was so terrified of ever letting him know the truth, even about her own past relationship.

As for Sonu being selfish and not speaking out, the only person who needs to forgive her is Ishqi. 

This is 4 lions they dont believe in speaking the truth...until some situation happens...and saying sorry is something the last thing the heroes does.so least expection from gullu

Both should introspect and try to trust each other. There is nothing for Ahaan to forgive her. He needs to assure Sonu that he will stand by her no matter what the truth is.
