It might be easier to think of a real-world example to use MVC in. Try not to analogize MVC with something in Rev or another environment that you may be used to, because what usually ends up happening is that one ends up sledgehammering a concept into a box that it doesn't quite fit into, damaging the perception of what that concept actually is.
Try taking something a bit more concrete, that you understand very well, and create a mental picture of what the Model, View(s) and Controller(s) might be for it. For example: a checking account. The model is strictly data. It could be a file on your hard drive, a database entry on a remote server, or even your balance book. The controller becomes the method by which the data in the model is changed. For our checking account, presumably there will be functionality to withdraw and deposit funds, transfer to another account, etc. The controller is how the user does this. The controller could be HTTP commands, functions in a script, or even the teller at your local branch. The controller doesn't even have to be a user interface. For example (purely for show): http://chase.com/deposit?acct=2938302&amnt=12.43 The view - on the other hand - is nothing more than the fetching and representing of the data associated with the model. It could be a bar graph showing deposits vs. withdraws over a period of time, or just a field displaying the current balance. It could be an ATM machine, a mobile phone, a web page, or something else. And just like the controllers, there can be many views all functioning at once giving you many different views of the exact same data set. What's important here is that each of these components are independent of each other, and they don't even need to all be present [together] to have a functioning "application." In fact, most MVC architectures are set up in such a way that this paradigm is magnified. In our example, the model is on a remote server at a bank. There are many views, and many controllers. Which view you are using right now has absolutely no bearing on what controller you happen to be using and vice-versa. You could be standing at an ATM making a deposit and see the new balance instantly on your Blackberry.
