Sam was thinking, which often could be troublesome itself. "Mr. Frodo doesn't remember anything," Sam murmured out loud. "It's so very strange that he doesn't. Maybe he doesn't have another...person yet." This whole concept of someone in his head, someone who was their person on another side of the door, felt very unreal to Samwise. "But no one else knows, either. Even Mr. Bilbo. He's not eleventy one yet, either! Eleventy nine, he says! How strange is that?"
He used his walking stick to kick the grass at his side, pushing it away so he had some room to walk forward. It's because none of it has happened for them yet, came the voice of the girl in his head. I think it's before for them. I'm not sure how, but I think that's what's happening. "That's all very strange, Miss Elinor. Maybe Mr. Frodo would understand, or Aragorn maybe," Sam commented out loud, humming himself as he continued to push aside the grass.
This Sam was more aware of things around him than the Sam who he had been before their adventures, but he still wasn't as aware as Aragorn or Legolas could be. He was enjoying himself kicking around the grass, happy that things were peaceful at the moment, though he was also concerned for the times to come ahead.
