Quotes from the article:

“She is very rare, very elusive and very wild,” says Dean DeBlois

On one level, it’s the emotionally clumsy Hiccup who has to train his fierce, but clueless dragon companion in flirting rituals.

“Toothless is a complete bumbling amateur when it comes to issues of courting,” DeBlois says. “He isn’t in touch with his primal instincts for these love matters.”

But as his relationship with the Light Fury flourishes, it pulls Toothless away from human influence.

“The Light Fury is an engine of change in our story, representing the call of the wild, which is key to Toothless’ destiny,” says DeBlois.
