Legolas had always felt lonely during these centuries in Middle-earth. His family had always been preoccupied with royal duties, leading to a very solitary childhood. This was the first time he felt complete since he started wandering the forest in the company of the dragon. The creature wasn't with him out of duty, like the courtiers and servants that attended his family. Sáro was not a mere beast trained to follow him everywhere he went. No, the dragon was a free spirit and seemed to enjoy his company more than anyone else.
