In fact, when coming to New York to attend this ball, Donnie had already guessed that Jack Morgan intended to play the role of mediator.
This made Donnie have some apprehension towards Jack Morgan.
Although these people now seem to have deeper ties with him, and before this, the Rothschild family had already acted against the Deep Sea Bank, yet the other party is still willing to step out as a mediator.
This indicates that if their cooperation is really that solid, it's something visible only on the surface.
The Rothschild family controls European finance, the Morgan family controls American finance, and the relationship between the two families is inevitably more complicated than one could imagine.
"For the sake of Mr. Morgan, I am willing to make concessions!" Donnie said in a deep voice.
This answer brought a look of delight to Jack Morgan's face, after all, once he intervened, Donnie showed support.
