Bod is a teenager when he finally confronts his conflict with the Jacks, of course, he thinks there is only one Jack through all those years. His first conflict with them comes when he goes to the pawn shop. After being trapped in a room, Liza Hempstock appears to save him by teaching him to Fade like a ghost. He listens to her lesson and she manages to get him safely out. On the way out, he has so much presence of mind, even in dangerous conflict, that he manages to find something to take with him--a paper weight--with which to make Liza a headstone for her unhallowed grave.
The next conflict with the Jacks is with Mr. Frost who is living in Bod's old house and is Bod's old enemy--the Jack who chased him when a baby to the graveyard. Upstairs in the nursery, Mr. Frost, alias Jack, tries to kill Bod. While he is escaping, Bod has loyalty and foresight to drag Scarlett with him when he Fades to safety. Finally, all the Jacks converge on them in the graveyard.
The sound of shoes slapping against the pavement, and two men were on the other side of the gates, rattling them, pulling at them.
When he and Scarlett are being pursued by the Jacks, Bod demonstrates a great memory: all the places where he found trouble in the graveyard are the places where he gets rid of his present trouble. He sends some of the Jacks through the ghoul-gate and one down an empty grave. The worst Jack, Mr. Frost, Bod tricks into claiming power to rule over the Sleer. The Sleer then appropriates Mr. "Jack" Frost and takes him into his barrow lair--forever. Jack has courage, calmness in the face of danger and cunning to shrewdly save himself and Scarlett from harm--with Silas aiding by taking her memories of the night:
"How is she?" [Bod asked]
"I took her memories," said Silas.
