Overall the chapter is well done, and things like the goblins' song and the descriptions of the dwarves in the trees are chuckle-worthy.
Some brief observations and thoughts:
1.It seems Gandalf is practiced in knowing when someone is lying. He didn't believe Bilbo's explanation of how he escaped from the goblins, even without knowing of the Ring and its potential influence.
2. Gandalf was apparently
ready to give his physical life for his friends, as he later did in Moria.
3. The way G. gets after the Wargs has its own callback moment when the Fellowship is attacked by wolves on the way to Moria.
4. Bilbo's reaction to the eagles is rather like a wild animal's, in line with his being said by one to even look like a rabbit in the next chapter.
5.The
deus ex machina of the eagles' rescue is plausibly explained, and Tolkien knew just how often he could use them without the reader rolling his eyes.
