Does Gandalf tell the dwarves that Bilbo is a spy?

Answer 1

When?

At the beginning, Gandalf the Grey chats to Bilbo saying he is looking for someone to go on an adventure. Bilbo, being timid at the start, is a little rude to Gandalf, but invites him to afternoon tea. Gandalf laughs and with his staff marks the front door "burglar for hire, etc". Later a knock on the door and after a while 13 dwarfs and Gandalf are in Bilbo's Bag End residence: Dwalin, Balin, Fili, Kili, Gloin, Oin, Ori, Nori, Dori, Bifur, Bofur, Bombur, and Thorin Oakenshield.

During the adventure Bilbo is separated numerous times from the dwarfs, and aids them in their escapades with his new found confidence and bravery and his magical ring.

Answer 2

No, Gandalf never told the dwarves that Bilbo was a spy. He was a good friend of Bilbo's, and they trusted each other.

Answer 3

From the 2012 film he says "True courage is not knowing when to take a life, but knowing when to spare one." This foreshadows Bilbo sparing Gollum.

Answer 4

While he was preparing himself a second breakfast, Gandalf came him and told him to check the mantelpiece. The note from the dwarves was there.

Answer 5

in chapter 8 after they fight the Spiders
