Lucy would OUTRIGHT HATE her father to the point of no chances in reconciliation if Jude took away the Gate Keys his wife entrusted them to their daughter.

Since Jude was way too buried in his business, I highly doubt he'd notice Lucy training behind his back while with paperwork. Even the servants won't tell him out of spite because they were there for Lucy. Besides he may the head of the Heartfilia business but Lucy is his heir so she may have some power and influence to get the necessary training and resources for becoming an independent and a mage of Fairy Tail in her right.

Right?
