Grendel's mom fights more; pins him and has dagger.
Beowulf fought in both battles.
Explanation:
The difference between the battle between 'Beowulf and Grendel's mother' and 'Grendel and Beowulf' is that 'Grendel's mom is more attacking, she carries a dagger and even pins him.' In return, Beowulf counters her with the sword and breaks her collarbones. The importance of the similarity between the two distinct battles is that 'Beowulf took part in both of them.' Apart from the battle with Grendel's mother, he had an intense battle with Grendel too where the latter attempts to swallow him. However, Beowulf was successful in trashing him down.
