20. <<<SPOILER ALERT>>> There has been a lot of controversy surrounding the show’s ending on whether Robin really loved Ted or if she simply agreed to be with him out of fear of loneliness. There is a deleted scene of the finale that shows Robin revealing her true feelings to Ted after all these years. Claims have been debated on whether Robin had actually lied to Ted after he asked her if she loved him. Some say she only rejected him out of her fear of tarnishing his dreams of having children or losing him as a best friend. Watch it here.
