Now that is devotion.
Samwise has two unshakable beliefs:
1. Master Frodo is completely unstoppable and can do anything.
2. Master Frodo absolutely, positively, under no uncertain terms, needs him.
Frodo and Sam’s relationship is one of the most profound friendships in the history of literature. Their relationship is the very heart of the love described in philia is about.
I love that Spike just lets him hug him.
