What happens to the Giver’s memory of an event after he transmits it to Jonas?

The giver does not remeber it.

Explanation:

Had to look for the said quotation taken from "romeo and juliet" and i can say that the italicized word is a possessive pronoun. when we say possessive pronoun, this is the kind of pronoun that shows ownership. examples of this kind of pronoun include "my, her, his, theirs, and ours". hope this answers your question.
