Difficult to say given the meaningless names you provided. Just in case, you can still split things nicely in 2 classes and still get Dependent to be the same thing than Obj : by inheritance. It is a common way to extend one class's features.

class Obj
class Dependent(Obj)

But do it only if Dependent **is** actually an Obj.
If Dependent not an Obj but part of an Obj, then your original implementation is probably the way to go.
