Aastha has mellowed so much that I am afraid to keep any expectations from her any more. She started mellowing right after getting shot but some spunk returned when she forced Tej to allow her and Anokhi to see Shaurya. But ever since Devi extended dosti ka haath, she has turned completely ineffective.
I agree with @dramacrazy though that Aastha doesn't force anyone. That is a character trait that has remained intact since the beginning, even the flashbacks. It is like she has a tendency to let it go, (her critics will say giving it up). Perhaps it has something to do with coping with loss. I am certainly overanalyzing but she lost her younger sibling and was learning to let it go. She let go off her rights on Shaurya Shaan and SM too easily instead of staying put and fighting it out. Perhaps she thought her going away would stop the conflicts in the family. It is not like she loved Shaurya and Shaan any less than her parents. Neither is it that she cannot fight. She was repeatedly threatened and humiliated by Ramesh Bhalla and yet she didn't stop fighting for Anokhi. She can answer back to Tej and Devi when required. She took on a goon like Raja so I don't think she was afraid to take on the Sabharwals. Though her decision turned out to be completely wrong.
This time around also I think she will not force Anokhi to fight for Shaurya if Anokhi decides to stay away on knowing about Shaurya's engagement and thinking about her own career. As for Shaurya, I don't know if he will be willing to give her a chance to even speak. She has much less rights and power over Shaurya than over Anokhi. But since she knows that both Shaurya and Anokhi want each other but are forced by circumstances to go different ways, I hope she doesn't let them repeat her own mistake and take some substantial steps to at least make them reconsider their decisions.
Devi is pushing Shaurya away from herself with these manipulations. I believe Shaurya is able to see through her act. But his indebtedness to her will force him to get engaged to Shagun.
I hope Aastha and Shaan are not relegated to the background and become ineffective props like Gayatri who speak but no one listens to them. The Shaan that we are seeing now would have made for an interesting character if we had not seen the previous Shaan. Had Shaan been a more responsible father to Shaurya from the beginning like in the OG, him being opposed to Anokhi would have made more sense. I don't know if after seeing how Anokhi single handedly rescued Shaurya, he will be more accepting towards their relationship.
