 Back in Little Weirwold, Willie gradually recovers from his injuries and reunites with Zach and his friends.Willie learns about sex from Zach, which his mother raised him to believe was "something dirty" and realises his mother must have been having a relationship with a man, resulting in the birth of Trudy.He questions Tom about this and Tom tells him gently that it is clear that Willie's mother was very ill (intimating her abusive and contradictory behaviour was caused by mental illness).
