Yes, as Dan and Amy are the main characters in all of the 39 clues series
To me,they are just friends.He was very nice to Amy and Dan ever since Book 5.Also in Book 6,he saved Amy from Isabel Kabra.They make really good friends.
Here are some of the many characters in the 39 Clues. They are listed by branch. Lucian: Isabelle, Ian, and Natalie Kabra Irina Spasky Ekaterina: Alistair Oh Ned, Ted, and Sinead Starling Tomas: Eisenhauer, Mary-Todd, Hamilton, Reagan, and Madison Holt Janus: Cora and Jonah Wizard Madrigal: Grace Cahill Amy and Dan Cahill Nellie Gomez Fiske Cahill
my opinion is that they are just friends.i don't think so. he saved Amy from the kabras in book 6. he helped dan climb the pole in book 9 so it would hep dan and Amy. and ever since book 5 he has been really nice to Amy and dan even though his dad doent like it and his sisters make fun of it. (im serious about the dad and sister thing. look it up)
