I believe cue is confused, I believe the part he's talking about is when MC and Asterion is in the restaurant/bar and he fabricates a normal bottle of wine and asks if you want some
You're correct! I don't often replay that part, so I forgot you gave him the wine before meeting Argos. He materializes the wine, drinks it at the same time Hestia's flame is kicking in and then the next time you see him he is half-healed.
