As the narrative unfolds in Chapter 20, the atmosphere around the cabin is thick with tension. White Fang, possessing an intuitive sense for his master’s moods, senses that "something was coming, something he would not like." The domestic environment is disrupted as Whedon begins moving belongings into "boxes and trunks." It becomes clear that Whedon is preparing for a journey to California, a destination where he believes he "can't take a wolf." The conflict is emotional and practical: Whedon feels a deep sense of responsibility, questioning "What am I supposed to do?" while Matt prepares to assist in his departure, acknowledging that the wolf is "on to" their secret plans.
As the time for departure nears, the cabin is filled with the "low, very sad whine" of White Fang. Whedon struggles with the guilt of leaving his loyal companion behind, noting that it would not be "fair" to take the wolf to a new environment. In a moment of poignant intimacy, Whedon bids farewell to his "old friend," asking for one "last good goodbye growl." Whedon’s internal struggle is evident as he sheds tears, unable to look back as he exits the cabin, intentionally shutting the door to trap the wolf inside to prevent him from following. As they walk to the boat, the sound of White Fang "scraping at the front door" serves as a painful reminder of the wolf's desperate longing to remain by his master's side.
Once Whedon and Matt arrive at the boat, their conversation centers on the hope that White Fang will eventually forgive them. However, a sudden "commotion on board" changes everything. To their absolute amazement, White Fang appears on the deck. Upon inspection, Whedon observes "fresh cuts along his muzzle and matted fur," realizing that the wolf had "jumped through the window" to pursue them. This act of sheer determination and loyalty leaves Matt speechless and Whedon profoundly moved.
Witnessing the physical toll the journey took on White Fang—the cuts and the matted fur—Whedon realizes that the wolf’s commitment to him is absolute. The realization that White Fang would risk injury just to stay with him shifts Whedon’s perspective entirely. He abandons his previous plan, telling Matt, "Don't worry about writing to me about the wolf, Matt. I'll write to you instead." In the final moments of the chapter, Whedon tenderly rubs the wolf’s belly and scratches behind his ears, declaring, "White Fang is coming home with me." This resolution highlights the profound, reciprocal devotion between the man and the wolf, ultimately proving that their bond is far stronger than the constraints of geography or the challenges of travel.
