In MC, after you ride the cart for the first time, Exlo asked about Link's Grin he had. That must be the only one of Link's emotions in MC, but that is partialy proof that he has a sub-limited personality that can be changed by perspective.
When it comes down to it, it depends on how you perceive Link's reaction on the 3D games. Some people would say Link is rebeliouse because did not want to wear the Hero's Clothes on Outset. But someone else would say Link is crying for joy when he recseives the Hero's Clothes on Outset.
