we've done outfits and hairstyles but which zuko smile was the best?

OKay, we can’t POSSIBLY rank those, so I have categorized them instead 

the ‘loves his uncle with his whole heart’ smiles  

the ‘receiving positive affirmation’ smiles 

the ‘loving and appreciating his friends’ smiles 

the ‘before everything went to shit’ smiles 

the ‘his goth gf makes him happy’ smiles 

the ‘being a sarcastic little shit’ smile 

the ‘you stupid fucking pirate’ smile 

the ‘this was probably Sokka’s bisexual awakening’ smile
