Implanting on someone?

You mean imprint,not implant.I will try to explain it.It's sort of like pag-ibig at first sight,but it's stronger.When a lobo imprints,the imprintee is the strongest candidate to continue the lineage of the lobo line.The imprintee becomes the center of gravity to the imprinter.Their every happiness is all that matters to the imprinter.Does that help you understand the whole imprinting thing better now?I hope I helped you to understand it better.

There are two distinct theories within the books. When people try to explain imprinting, they tend to only explain one of the theories.

It's a recognition of a soulmate, or the best person to continue the lobo line with. It happens whenever the imprinter first sees the imprintee after having become a werewolf (if they'd known each other before then, he wouldn't imprint until he was a wolf). When the lobo imprints, the imprintee becomes the most important person in his life. All other relationships and connections become meaningless in comparison, and its as if the lobo is held on earth sa pamamagitan ng the imprintee instead of gravity. In most cases, it's pag-ibig at first sight. Imprinting can also occur if the imprintee's a child, though, and in those cases the lobo becomes a protector first, almost like an older brother, then a best friend and then it becomes romantic when she's an adult.
