From New Moon to Breaking Dawn: the Evolution of Imprinting Explained
The climax of the imprinting arc arrived in the second half of Breaking Dawn. For three books, Jacob Black chased Bella Swan, insisting their shared humanity and natural compatibility outweighed Edward Cullen’s frozen, immortal attraction. Bella’s marriage to Edward and subsequent pregnancy pushed Jacob to the brink of pure vengeance.
Following Renesmee’s harrowing birth and Bella’s apparent death, Jacob marched back into the Cullen residence with murderous intent. He intended to tear the hybrid infant apart. The moment Jacob looked into Renesmee’s brown eyes, eyes inherited directly from Bella, the biological switch flipped. His rage vanished. The room dissolved around him.
The imprinting immediately dissolved Jacob’s romantic obsession with Bella. The unresolved tension that drove the series' central love triangle evaporated in a single heartbeat. More importantly, Jacob’s imprint activated the most sacred rule in Quileute shape-shifter history: pack law protection.
Under ancient tribal decree, no wolf may harm the chosen mate or imprint of a fellow pack brother. Doing so invites catastrophic civil war within the telepathically linked pack. When Sam Uley led his wolves to storm the Cullen residence and eliminate the newborn child, Jacob confronted him at the door. Phased into wolf form, Jacob projected the reality of his imprint into Sam’s mind. Sam was legally and culturally bound to back down. The wolf pack had to stand down immediately. The imprint served as a total narrative shield, securing peace between the Forks shapeshifters and the Olympic vampire coven.
