What does the disguised ariel say to the banqueters when the banquet vanishes? how does each of them react?

They are all amazed, but not too taken aback that they will not eat the food; but, as they are about to eat, a vengeful Ariel enters, taking credit for their shipwreck, and makes the banquet vanish. Alonso recognizes Ariel's words as being of Prospero's pen, and the great guilt of Alonso, Antonio, and Sebastian begins to take them over, at the thought of Prospero being alive, and so nearby.
