What does the set method inside pet looks for?
Kinda lost, when we call the object property it will go to the setter on pet and look how it must be instanciated then go for the Owner class and set with the method on the onwer class inside the pet instantiation, right?

The setter method "owner" on "Pet" does not create an instance of "Owner". But it does allow you to assign one, as is done by the example code:
ernie.owner = new Owner('Ashley', '123 Main Street');
The new "Owner" instance is created by the "new" keyword, and then assigned by the setter method in "ernie".
