Following Beowulf's victory over Grendel, Wealhtheow offers a toast to the Geats and gives Beowulf rewards for his heroism. She tells Beowulf " have luck with this neck ring beloved Beowulf. . . accept these gifts gold gleaming treasures . . . and use the well; may you win always. . . make known your strength and save for these boys wise counsel words. . .I"ll reward you for that" (XVIII). Wealhtheow cleverly uses this opportunity to safeguard her two children from Hrothulf. Should the king meet an untimely death, Wealhtheow needs to guarantee that Hrothulf does not steal the throne from her children, the proper successors. During her toast to the large crowd of Danes and Geats Wealhtheow turns to the king and announces "[she] is sure that Hrothulf . . . [her] kind brother son will care for [her] young ones . . . guide and hold them if [he] goes before him" (XVIII). She then adds "he will surely repay us shelter for our sons . . .if he well remembers how we watched over him . . .held him as our own gave help in everything . . . shepherded our kin through a safe childhood" (XVIII). Wealhtheow controls the situation and therefore has political influence as the woman behind Hrothgar. Wealhtheow's love for her children is noble and praiseworthy, but when Grendel's mother shares this sentiment for her son, she faces a completely different response from the men of Heorot.

Grendel's mother violates the role of traditional Anglo-Saxon female by being powerful and aggressive, but her craftiness makes her a stronger adversary than her son. The main distinction between Wealhtheow and Grendel's mother is that Wealhtheow's influence is much more subtle and nonviolent than that of Grendel's mother. Grendel's mother is a descendant of Cain and "damned to hide in a dark water-home" (II). Being a monster, Grendel's mother possesses "great warrior-strength" (II); however, since she is female, her strength is less than her sons.
