Aldo Edmund sent an antidote at Lorena's command.
Aldo passed on Lorena's words to Brandon. He said, "Mr. Young, Mrs. Young said that it could only keep Ms. Thompson's emotions under control temporarily. If you want to get the poison in Ms. Thompson's body out of the system completely, you must go back to Philadelphia."
Obviously, Brandon going back to Philadelphia was the prerequisite to curing Savanna.
And Aldo called Savanna Ms. Thompson, which showed that Lorena still did not think of Savanna as a member of the Young family.
Brandon's eyes were cold. He looked at the pill Aldo handed over.
Brandon was a proud man. He did not want Lorena's antidote. He even wanted to drive Aldo away.
