Actually the name is usually always spelt 'Aaron'.
The name comes from the Bible. It was borne by the brother of Moses in the Old Testament, and it is possibly of Egyptian origin.
Some ppl also use it as a male form of "Erin" since that means "Ireland".
The first thing I thought of was that Aaron was Moses's brother. *Moses led his people out of Egypt to the promised land in what book of the Bible? *Exodus????? *Hello!
I'm not a person of "the Book" but I have taken religious studies courses in college. *One thing I did learn about Aaron and Moses was that Moses was the one with the message & the mission, however he had a speech impediment: *he stuttered. *So therefore, his brother Aaron spoke for him. *Hence, Aaron = messenger/translator/transmitter. *My assumption is that Aaron (gosh, I miss calling him Turniphead!) will be the messenger/translator/transmitter of The Others. *This fits in with the theory that Aaron has been infected by "the infection" and possibly will infect the other Lostaways or else "the infection" will allow him an innate understanding of The Others and he will eventually be able to "speak" for them- possibly being a liaision between the survivors and The Others.
