The Power Broker persuades Batroc, an Algerian terrorist with a beef against Sam Wilson, to come with her to New York. There, she assists Wilson and his partner, Buckey Barnes, in trying to save members of the Global Repatriation Council from Karli Morgenthau and her gang of terrorists, even managing to kill one of Karli's super-soldiers with mercury fumes.
She then murders Batroc and tries to persuade Karli to rejoin her criminal syndicate. Later, we see that her criminal record from the events of Captain America 3 has been expunged, enabling her to expand her criminal work with government information and resources.
What was her goal in going to New York? Was it to recruit Karli? If so, why did she need Batroc and why did she help Sam and why did she kill one of Karli's people?
Was it to rehabilitate her reputation? If so, why did she try to bring along Batroc and try to recruit Karli?
