What about the fact that she said "Ty" in one letter and "Tie" for the other. That's a duality but they're both addressed to YOU. Therefor, YOU'RE at one with YOUR duality. Yes? No? Maybe?
Also, she's supposed to say that she's "one with her duality"... there shouldn't be an AT. The mistake could be intentional but I doubt it.
OR, the word duality has to do with her name somehow.
