An Uncertain Ending

An uncertain ending that left me wanting more.  Chapter 14 gave me the feeling of many "possibilities."  It wasn't a "final chapter," but rather a opening to something more.  Its kinda like when you come to a fork in the road, but with more than two options.  Escaping from it all to another place, marry Phyllis, or even suicide!  On page 113 Walter says, "Ive been thinking about something else.  Phyllis smiled then, the sweetest, saddest smile you ever saw.  "I thought of the five patients" she said.  "The three little children, Mrs. Nirdlinger, Nirdlinger, and myself.  It didn't seem possible that anybody that could be as nice as she when she wanted to be, could have done those things."  Walter then asks her, "What were you thinking about?"  Then Phyllis says "We could be married, Walter."  Walter replies, "We could be.  And then what?  The notion of uncertainty surrounds them, bringing almost a desperation to which way they should retreat.  "She started it again.  There is nothing ahead of us, is there Walter?"  "No.  Nothing" says Walter.  I almost feel sadness and pity for this "dynamic duo."  But like the saying says, what goes around, comes around, and that is exactly what happened to them.  Walter and Phyllis's relationship started, and then ended just as quickly, the same.  For two unforbidden lovers, found themselves going separate ways at the end.
