Dain is lowkey impressive
So, if we do the math, Violet gets assigned to the Quest Squad in January, and they arrive at Unnbriel about two months later. That means Dain had roughly two months to become somewhat conversational in Unnbrish, while also learning three other languages at the same time.
I know the fandom loves the “Aaric was never asked if he could speak those languages” meme and how he embarrassed Dain, but honestly, being able to get somewhat fluent in a language in just two months is incredibly impressive. Especially considering that Dain was learning three other languages simultaneously
Creds to sunsetrose7 on Tumblr for pointing this out
