To me, Sam seems to be defending Strider in that apple-tossing incident. I was pretty impressed since Sam is so slow to trust him in the first place.
I don't know about that, remember Strider's sword is still broken. Besides, Ferny is a coward, he runs away when confronted when the hobbits return to the Shire so I'm sure Sam could take him.
uh-oh, getting ahead of the story again...back to Tooks' corner
