Aiden is usually kind and friendly in the series. He is also immature and loves reuniting with his friends.

Also because Aiden and Zoe are just friends and George and Zoe are dating.
His first name, George is the name of the Celtic sun god, meaning "fiery." It was traditionally a boys' name but is now given to girls, too, especially spelled as Aidan. Well-known Aidens: actor Aidan Quinn; one of Carrie Bradshaw's boyfriends (Aidan) on Sex and the City.
