To me there is nothing so admirable as a passionate love-bond between two human begins. Sam loves Frodo and wants to protect him and Frodo is extremely protective of Sam. So what you have are these two people locked into this journey together. They don't need to explain what they are to each other, they don't need to talk about it; they just are.
