He is Gwen's father who once helped him around the kitchen. He cares a lot for his daughter but doesn't like it when she invents gizmos because he too once invented something that ended in disaster. Since then he tries to persuade Gwen to just be a kitchen maid and stay away from inventing because he didn't want her to be as humiliated as he'd felt.
However, he finally changed the way he saw his daughter's talents when she successfully built a bowl painting machine for Amber's berry banquet. For the first time ever he was proud of her, and she even repaired the pudding-serving invention he originally made, pointing out it had just been missing a screw.
Andre is the typical stern father who tries to dissuade his child from goals he deems folly or silly, but in his defense, he was only trying to protect his daughter from the same humiliation he endured
