Closing a Modal (via delegate) from a different View

I'm hoping that i'm simply overlooking something simple. But here the scenario.

I have a root vc that opens a modal view LoginScreen. In that view class I've set up a protocol (ViewControllerDelegate) synthesized, and once a user logs in via the modal, the parent VC closes the modal and all is well.

In LoginScreen.m to close the modal all I have to use is this code:

[self.delegate loginConfirmed:self];

That works perfectly. However, I have another view that gets pushed is login is confirmed. Still as a modal of course. Call it LoginScreen2.

I can't figure out how to get the Modal to close from LoginScreen2 and get back tot he root VC. I've tried a bunch of different variations like this, but no luck.

[((LoginScreen *)self.parentViewController).delegate loginConfirmed:((LoginScreen *)self)];

I've been searching and messing around for a couple hours, with no luck. Again I'm hoping I'm just missing something simple and just not seeing it. If anyone has any ideas that would be awesome.

Not sure who is presenting the second view controller, but one thing that might help you is to know that a modally presented view controller can dismiss itself: 

[self dismissModalViewControllerAnimated:YES];

The root view controller can check the user state when it appears, and presentModalViewController:Login1. Login1 changes the user sign-in state, and dismisses itself. Root sees different user state (when it's about to reappear via the viewWillAppear: method) and presents modal on Login2. No delegation needed.
