Two Frodos

[TarElendil]

And Sam was the servant. There was some affection there perhaps, and certainly some loyalty (hence Sam's choking under the window when he realised Frodo would leave) but nothing whatsoever to imply as close a relationship than Frodo had with his uncle.

I think sam and frodo's relationship as friends was no smaller (if not more) than Bilbo and Frodo's. Its just on two different grounds.
