How many times did we saw a squirel over the course of the story?
The squirel have been a recuring "himaginary" friend of Hawk for a very long time, and, now, here he is ALIVE!

Is he an imaginary friend that he can see? Is he a real quirel and Hawk forgot that he was once real and became an imaginary friend? Is he realy a ghost of the original squirel friend?
Questions, questions....
