Former steward to Sam Tarly's boss, animal lover and incel Chett, is organising a rebellion against and escape from the watch on account of he thinks he's on the losing side. He reckons he can do away with old Craster and have his wives and daughters (same people).
In between kicking dogs and taunting Sam Tarly, he makes sure his merry band know who they are supposed to be killing and when, and waits for the third watch. Except it snows, which ruins all his chances of escape because it's really easy to follow people in the snow. So he goes to kill Tarly anyway in what seems like a pointlessly self-destructive act. But he's saved from his foolishness when three blasts of the horn sound and Tarly wakes up. But three blasts means Others, so he might well be dead anyway, and in a much scarier way than he'd expected. So he wets himself.
Ah, that chapter had a little bit of everything. Good to see GRRM is still on form!
