How will Beanpole help Will and Henry on their journey to the White Mountains ?

Who is Zhanpole? Zhanpole is a unusual charter that wears glasses and speaks english. He is about to join Will and Henry's journey to the white mountains. Will and Henry call Zhanpole "Beanpole".

I think when Henry and Will meet Zhanpole (beanpole) is important since When Will asked whether there was a place that the Tripods wont search, he remarked "the mountains". Not only that he knows where the tripods wont seacrh, he also knew the way to the mountains.I think Zhanpole will be easy to get along with later in the book since his real name is Zhanpole but then Henry nicknamed him beanpole and he didnt get mad at all and thats why i thnk it easy to get along with. This also gets the reader hooked up by making Wills journey start. And also Zhanpole cooks food for them.
