When Neville awoke as a Guide he was just five years old. His grandmother sequestered him away and helped him hide his gift, even if it meant that everyone thought him not much more than a squib. To be a Guide or Sentinel in magical Britain is a death sentence. When Neville comes to Hogwarts, he recognizes his Sentinel in fellow Gryffindor Harry Potter, but is delegated to the sidelines while Harry’s life is in peril every year. When Harry loses control over his senses at the end of fourth year, Neville needs to act with haste to save him.
