In episode 293, you mention Merry asking specifically about the "Speak, friend, and enter". I don't think we should find it surprising that a Hobbit would have greater sensitivity /ability to identify a likely riddle in the door's text, compared to any of the other races. To be fair, nobody would be expected to know this besides Gandalf, but he still didn't listen. But I love JRRT highlighting this trait, as if highlighting "Leverage the strengths of EVERYONE in your troupe!" Thoughts?
