Everyone saying that Aaliya shown to be mature till date and today she is totally unfair with her own maturity and actions. But her actions and anger is justified today...
Aaliya and Aayath came from family where their parents always teach them honesty and values of the life. They brought up both AA sisters with very rich values of life SO when today Aaliya found that her own sister lied to her parents as well as lied to her appi its a big shock to her. Because in her family such things never happened before and they all consider Aayath to be a very nice girl. So her anger justifies because Aayath's lie is big setback and destruction to the values taught by their parents. It indicates her parents izzat and parvarish failed big time...
Yeah...Aayath is nice girl and whatever she did is to help her parents in paying the debt but she took the wrong path...In attempt to help her parents she forgot other dangers and trusted the wrong person. In process she herself suffered. Here I think CVs shows one common issue which happens many a times...Don't trust person blindly who you met on social media ...if you do that result might be destructive.
One more reason for Aaliya's anger might be due to the threat to Zain because now she knows Rocky is the person who brought Aayath in Mumbai...blackmailed her and Zain save Aayath by arresting Rocky...resulting now Rocky is behind Zain. Aaliya already started loving Zain (although she is not yet realized that).
With all this...its very difficult to act mature when your family's pride and your loved one's life come to danger because the person you trust act foolishly for whatever reasons.
So..be calm..take it easy. Aaliya wasn't wrong today.
