Upon arrival to Burgess, the others found themselves in the middle of a mess. Children all wandering towards the witches' cabin in the woods, surrounding by a magical dome that didn't let in any adults, the adults all wandering towards the party at the local community college, where the adults were under a spell meant to cause them to dance themselves to death.

The songs, fortunately, had stopped by the time they arrived, but with all the kids inside the dome and all the adults entranced at the party, they had to find some other way to break the spells aside from brute force.

Which meant killing the witches.

Fortunately they had time - at least according to the talking cat that appeared when they tried to break into the dome, claiming to be an enemy of the witches. Apparently peeking inside meant he saw that the spell was draining the life from Jack and the other young myths because they had a surplus of it as myths. Jack in particular had a ton of life energy due to his long unlife and the belief the kids had in him, and it meant that it'd take a long time for the spell to drain the life from all the kids to kill them. It was sucking them all dry, but while Jack bore the brunt of the spell, and then the other myth children that were part of the team next, all of the kids would live.

Until he rain dry. Once he was nearly tapped, the other myths kids all would run close to empty, too, and then the mortal children - and they'd all die at the same time.

Which mean they all had a very important task to accomplish - alone. Other than the team members that had shown up, backup from the Pole wasn't coming, since all the others were out dealing with putting out other fires around the world or not ready to leave the Pole and fight yet.
