Don't forget that the term "teenager" was only coined in the 20th century (H.L. Menken predicted, some say accurately, that the invention of the word would be bad for civilization). In Anne Rice's "Interview with a Vampire" Louis describes how he, as a teenager had all of the responsibility of an adult. Alexander Hamilton ran his own export business at 13. For Tut to have had great authority, even at his young age, is not unimaginable at all. As a matter of fact, it would be historically accurate for many of the historic leaders depicted here to be much younger in appearance.
