I'm starting to feel like Aliya is intentionally spoiling rhea to make sure rhea stays under her control. Like she perhaps sees rhea as an investment in order to keep control and power over the house. This is the only way I can explain why aryan doesn't even seem to have a mother despite living in the same house where his mother loves. All of aliya's scenes where she tries to behave like a parent is with rhea, whereas she barely talks about or is ever seen with aryan. I'm guessing she completely had no hand in aryan's upbringing and it was purab alone, because aryan has turned out to be a decent and sorted young man who isn't problematic or full of attitude and disrespect like rhea or his own mother, aliya for that matter.
