Dedicated to grey_wonderer because she had the best paragraph in one of our impromptu chats about how multi-layered Samwise is (and other fanficcy matters) and yes, he is a very important hobbit. :)
And Frodo did know in the beginning about how multi-layered Sam is- "I am learning a lot about Sam Gamgee on this journey. First he was a conspirator, now he's a jester. He'll end up becoming a wizard- -or a warrior!" -Flight to the Ford
Post quest conversation with the hobbits:
“How did Sam rescue you, Frodo at the Tower of Cirith Ungol?” asked Merry.
“I never knew Sam to be so brave. It was so important that he went to Mordor with you,” said Pippin.
“Sam also made sure I drank and ate since the Ring was bearing down on me,” said Frodo quietly.
“It was just my duty,” said Sam with a blush. “Mr. Frodo has had the hardest time after all.”
“He genuinely is the real hero,” said Frodo, looking at Sam with respect and love. “He has grown so much. Frodo couldn’t have done it without Sam.”
