In this third description of Edward’s death, William is starting to realize that Edward’s “facades” (frustrating as they are) simply
are who Edward is: Edward can ‘t be any other way. William begins to realize that he needs to accept his father as he is, rather than try to change him, if he wants to feel the connection and love that he craves. As William starts to give in to this notion, he becomes “filled with wonder,” indicating that Edward’s stories and jokes really do fascinate William and are a big part of why William loves Edward, even he can’t fully accept this fact yet.
