Need help answering a fellow classmate's response to a discussion question.

Discussion Question

"Beowulf" includes, as a small embedded narrative on lines 1687-1698, an account of the Flood from "Genesis" and "Gilgamesh." How does this abbreviated account compare to the others?  What point of view does it follow?  Why does this account seem to be included?  What purpose might it serve for the overall narrative?.

Classmates response

Grendel's Mother is a survivor of the Flood, though she would have been one of the beasts that helped encourage the wrath in the first place. It serves to remind the listener that she is a daughter of Cain's line. A monster, not born of nature, but of the Curse Cain was given by God after the murder of Abel. Her previous nature is not known, but after the flood she has develop an aquatic nature. It is a reminder of her nature, but also a bit of empowerment. She is no run of the mill hag, or dainty sprite. She is living, breathing defiance of the Judeo-Christian God. She is a match for Beowulf.
