Only one of them is real, can you tell which?
Nerin doesn't normally smile on his own, he doesn't make that many expressions at all, but he's taught himself to smile so others don't worry about him. He's gotten pretty good at his fake smiles, it's very hard to tell they aren't real.
His lack of smiles doesn't mean he's depressed or is never happy; he just doesn't express himself very well and he's always been like this, even as a small child.

Aw... Nerin's little smiles. He's so cute, but he should really stop eating cucumbers.
