Firstly, onscreen, what is up with this special appearance of Aashi? D3 has never been consistent in story, or character presence. I really like her character but unfortunately hers and a few other roles are too inconsistent. I honestly don't mind not seeing the rest but generally there's no consistency with missing characters. Possibly, these actors are pursuing some other job.
Secondly, offscreen, unfortunately the "CVs" get blamed for everything wrong happening. Let's first define what exactly is a Creative departments job in this show and then blame a particular person. Now that I've done that, I'm gonna blast the following -
the story writer, the director and the screenplay department for their amateurish work. I request them to work more and not rely on the SS and KR fan base to watch their show inspite of the badly written work. I'm sorry to say but the work they show is for KG kids. I'm in college but I really feel this show treats its audience like kids who'll accept anything they produce. I want some sensible story, sensible work. I want the show young but not so young ki practicality ko hi bhula de
