What is Humblebee?

After Artos catches Guen and Bedwyr together, he banishes them. The next day he is sitting in the audience, listening to the commoner’s grievances, and acting as a judge, when a humblebee flies into the room. It keeps banging its head against the wall trying to find a way out. Artos thinks to himself that he feels like the bee, with no escape from the pain of his double loss.
