Who does arya like?

So far, and presumably, Arya only regards Eragon as a friend. However, it is somewhat hinted that she may have possibly had some feelings for her deceased elf friend Faolin, who was apparently killed along with another fellow elf friend when they were ambushed by the Shade Durza while escorting Arya as she ferried Saphira's egg between their own elf people and the Varden. Other than that, we will probably find out more about the true answer in the fourth book of the Inheritance Cycle.
