Magic: "On the contrary, we will provide you with some conveniences to ensure you can achieve greater success..."
Magic mentioned the Lucerne City business tenders. As the heir of the Lando Family, Wayne's personal interests were highly tied to the Lando Family's interests. The intelligence agency was eager to see Wayne stabilize his current social status and was willing to divulge some information to help the Lando Family's business grow stronger.
In turn, Wayne would continue his old trade, transmitting information about the Tulip Family and the Royal Family to Frank.
If everything went as expected, Wayne would live a life of glory and wealth as the head of the Lando Family, never crossing paths with Frank again in death.
If things went awry, Magic didn't say, but he trusted that Wayne knew how to assess the situation.
Cooperation would benefit both parties, communication would mean a win-win; there can be no mistake.
