Willow told him: "I don't know, Dad, I'll have to see if I can help them, but if their bodies are healed and they drank a potion against mental fatigue then it's probably just that their minds haven't realized that they're fully healed yet, and they haven't lifted their protective barrier which is to put them into a coma to force them to rest."
Axel was thinking the same thing, which is why he said: "So there's a good chance you can help them, isn't there?"
Willow nodded, but told him anyways: "It's the first time I will try to bring someone out of a coma, but it should be similar to what happened to Daddy and Miguel, only I don't know if my psychic powers will be enough to bring that many people out of a coma."
Axel then said: "Don't worry about that, just do your best and no one will blame you if it's not possible, or if you don't have enough power to bring them all out of the coma, OK?"
