How do I get the node/entity from an instance of entity_metadata_wrapper in Drupal 7?

Question

How do I get a reference to the node/entity used to instantiate entity_metadata_wrapper / EntityDrupalWrapper. I could not find a getNode/getEntity or similar method in the EntityDrupalWrapper API Reference.

$wrapper = entity_metadata_wrapper('node', 
        entity_create('node', array(
            'type' => 'video',
            'bundle' => 'video'
        )
    )
);

EntityMetadataWrapper provides two methods for getting node data, raw and value. Description of raw from EntityMetadataWrapper API Reference.

Returns the raw, unprocessed data. Most times this is the same as returned by value(), however for already processed and sanitized textual data, this will return the unprocessed data in contrast to value().
