What was interesting to me reading the books is how Pippin is basically the Hobbit version of a young Boromir or Faramir (I mean, physically they’re roughly the same age, but in Hobbit terms Pippin was considered to just have barely left childhood), but he grew up in a land of peace and plenty.

I wonder if Tolkien was using him and his family as a contrast to Denthor’s family, which is why it’s Pippin who goes to Gondor. The Thrain was even one of the leaders of the Hobbit resistance against Saruman, for further parallels.
