Yes, she was Snow told David what about the Blue Fairy speaking over Ruth, and Lancelot said that it was poison and the BF couldn’t help when he tasted the arrow that is when David suggested the Lake.
Here is part of the quote:
In the Fairy Tale Land of the past, with Charming and Snow still hovering over Charming’s wounded mother, Lancelot tells them all that the arrow was poisoned. Even fairy dust can’t save her at this point. Suddenly Charming remembers: Lake Nostos
They weren’t talking specifically about the Blue Fairy, but fairies in general. I tried to find “Blue” in the episode transcript and came up with nothing, a little more clarification would’ve been nice. 🙂
To be fair with Blue and fairies in general, though, magical poisons have been shown to need far more than the usual, common magical resources to heal. Rumple certainly didn’t think something as trivial as fairy dust could heal Hook’s poison in “The Miller’s Daughter”.
