Sylas returned to the Amazonian Wilds on the same day. His target this time was different. He needed a method to bring Brant's family back, and that obviously entailed transportation and a plan of action.
The best plan was to take them out separately. He would deal with Brant's wife and child, along with Olivia, while Brant would leave via his own method.
First, he went to catch more Blue Cyclone Horses. This was more difficult this time because there were no leaders left after he conquered their head. So, they had become more scattered and had broken into several factions.
But it was an easy enough affair. It took Sylas about three hours after scouting the general area they frequented to catch three more.
