On Enduring Pain

 

There is no real going back.

There are some wounds which cannot be wholly cured.
GANDALF

Having been key in averting utter disaster for all of Middle Earth, it is a great tragedy is that Frodo cannot benefit from what he has achieved.  Sam feels the injustice most keenly; aware that few know (or care) what his master has done and sacrificed, and heartbroken that even in anonymity, Frodo cannot enjoy the Shire that he saved.

It must be so, when things are in danger:
some one has to give them up, lose them,
so that others may keep them.
