Hal left the Alchemist organization building with Arya and Karmen only to board his carriage which had been kept well at the building and ride to the residence the alchemist organization provided for them.
While they rode along with Arya in control of the carriage's movement as she was the one who had actually been told of the residence's location, Hal decided he would be going over to Dane Territory.
The inhabitants might not be pleased to see him but he was not going for them but for his woman so he saw no reason to care.
Other than the fact that they could kill him of course.
The carriage stopped in front of the residence which turned out to be a large mansion that was even bigger than the one Melinda had had in Sapphire city.
