[Eomer of the Rohirrim]

My mother was getting a bit suspicious of Sam when she was reading the book. She thought he was being a bit too nice to Frodo.

So I told her that Sam does indeed turn character, murder Frodo, claim the Ring, become the New Dark Lord, come close to enslaving the entire world, but Frodo is avenged by Merry, who kills Sam and becomes King of Middle Earth. (Pippin having been killed in battle with Sauron)

Needless to say, she didn't believe me!
