The internal prototype is not a property so it doesn't show up. Some browsers expose it as __proto__, but it is not enumerable and is non-standard.

Similarly, 'internal scope' is not a property, for example you can't do obj['internal scope[[scope]]']. Chrome displays it in the console to be helpful but it a property of the object.
