A Blessing of Stone and Water

Apparently if you still have the food you cooked with Murielle and Bhatair in G23, Murielle will comment about it in this quest, saying she can smell it on you and asking if it's gone bad before asking what brought you to Filia.

Same goes for Bhatair in Pure Thoughts. Though, they talk about how your character stinks because you've held on to the food for so long. x'D
