In the video, Iglesias is depicted as a jail prisoner who receives limited visitations with restricted contact from Barton, implying he is addicted to her, and cannot have as much of her as he wants. At the end of the video it is realized that there is no prison, and he simply is addicted to her.
In the context of the video, Iglesias's limited access to Barton symbolizes his inability to cope with his intense emotions for her.
