Grand Plan

The reason why Bryan was trying to involve the two kids in his plan was that their families were business partners in a certain venture. And this venture just so happened to be in association with Nicholas Tenant.

Bryan had happened to glean this information by questioning Dillon in his dream. Of course, the latter didn't know anything about it. What he was looking for now was for their family to introduce him—Anthony Wayne—to the people behind Nicholas's new venture as an investor.

From there he could work his way up to meet up with the man himself. And then, once he's gained Nicholas's trust, he would rob him dry. He wouldn't even leave a penny behind. That was the plan that Bryan had come up with.

Of course, he could have done this whole thing without the involvement of Meryl and Dillon's family. But having their family introduce him made it that much more credible. And as for the backlash that their families might face after his heist, that was none of his problems.
