¨Oh Hal, you mustn´t. The poor dears! Now you must promise you won´t be harsh with them for the rest of the trip,or else I won´t go another step.¨
GET OFF THE SLED!
This was when Buck and the rest of the team are really tired and have basically no energy and Mercedes tells Hal to stop beating Buck because she feels bad for him.
Buck had to pull all the stuff that Hal, Charles, and Mercedes brought plus Mercedes because she was to sad and weak to walk herself and Charles and Hal don't like it .
Hal and Charles are trying to get Mercedes off the sled because they don't want her to be on there throwing a tantrum and being annoying when they have to go through the same thing she does.
After Hal beat him with a club, Buck lives with John Thornton and goes back to the law of the fang and is now hearing the call of the wild.
John Thornton dies from the Yeehats and Buck goes into a rage of fury on the Yeehats. He starts biting there necks out and doesn't even care about it.
Buck is now living with the wolfs and loves it because he lived like a wolf when he was with Francois and Perrault and Spitz and Sol-leks. Now he really gets to embrace his inner wild, and go back to the law of the fang, and listen to the call of the wild.
