How does London present motherhood and fatherhood of the two wolves in the next three paragraphs? of the liar

I think there is a sense of both fear and partnership in the chapter. The she-wolf is very wary of One Ear, and growls at him when he comes too close. "Of her own experience she had no memory of the thing happening; but in her instinct, which was the experience of all mothers of wolves, there lurked a memory of fathers that had eaten their new-born and helpless progeny."

Soon he leaves, realizing he must get food for his newly born young. Meeting a porcupine, he knows its tricks; he was a victim of its quills before. At the sight of the wolf, the porcupine rolls up into a ball of quills. One Ear lays down a foot away, waiting for it to unroll. Eventually he just gives up and moves on.
