I don't doubt that Alia can get movies on her own -- but so far it's obvious she has done movies that KJo has gotten for her and told her to do. Dear Zindagi was entirely facilitated by KJo. Alia apparently hadn't even read the script or met Gauri until right before shooting. Same with Highway -- it was KJo who got it for her.
All her next movies are with Dharma only. She has not bothered to even try to venture out. Of course it's been a mutually beneficial relationship for Kjo, but it's also not just about movies. KJo has literally played a huge role in her PR and creating her image, getting her exposure. The whole "Genius of the Year" was something KJo did as well, if I remember correctly. Kjo has, IMHO, singe-handedly made Alia's career. I truly believe she would not have made it without his backing. That;s not to say she doesn't have talent, but she's also not as amazing as she's hyped to be.
I felt like KJo didn't really care about the new debutantes, but he will spend some time on Jahnvi for obvious reasons. If she has some small amount of talent, then KJo might offer her more movies or go above and beyond like he did for Alia. There are rumors of Ananya and Sara as well. It'll be interesting to see how Alia goes from here.
