Regarding the Frost Faeries, Ceria ones said that she can hear whispers and see—something.

At first I thought that it was because she was a half-elf, but could it be because she eat some of the ingredient of the faerie's drink. We know that in the past she eat a bit of everything in order to survive, like bugs and tree bark, so she could have eaten some of the ingredient for the faerie's drink, not enough to break there glamor but enough to hear whispers and see—something. What do you think?
