It is only after reading all of the books in the Throne of Glass series and then rereading them now that I realize how wholly different Celaena is from Aelin. How much she grew and matured in Queen of Shadows.
Celaena was a girl. She was vain and haughty and enjoyed nothing but fine things and annoying the hell out of everyone.
Aelin is a woman. She is brave and strong and cares so deeply for others that she would give her life for them, a Queen.
And going back to Queen of Shadows and reading when she and Arobynn Hamel reunited, I know realize how hard it must have been for her to go back to Celaena. To the girl he had raised; the girl he had shaped and formed and made her into. I know understand how Rowan felt, watching her transform from the strong Queen that he knew to the little girl that Arobynn was so familiar with.
