I just watched this episode tonight. I like the fact that they replaced the ominous "bumper" tone with Christmas bells...The lasting effect that losing someone you love can clearly be seen in both Frank and Jordan, who goes from being ( most understandably) anti-Christmas at the beginning of the show to most poignantly giving Rose and Lhasa the gift she had been keeping for her mother. That Frank allows Eddie to escape with the girls provides the perfect ending for his seasonal episode. Frank and Jordan both arrive at the conclusion of the show with the understanding that, although Catherine may be lost to them forever physically, emotionally & spiritually she will always be with them.
For a program that never failed to show viewers the horrors that the world is capable of, it was a stroke of genius to show us two beloved characters, each alone in their own grief, starting to heal not only through love, but indeed through what can only be called a miracle.
