Look at the scene in Chapter 11, focus on the how Bilbo is presented when sitting there lonesone. Choose one quote. Do a PETE Paragraph and explore how Bilbo is presented.
When they reach the mountain it is clear that Smaug is still alive, for his smoke is all about the place. Again, Bilbo is the hero and he manages to lead them up the mountain and successfully decipher the runes of Thorin's map. But after this, Bilbo has to find the correct path; and after this, Bilbo has to find the doorstep. The dwarves may be excited about the treasure inside but they are not excited enough to enter the cave on their own, and so Bilbo must enter alone.
Bilbo found sitting on the doorstep lonesome and wearisome—there was not a doorstep, of course, really, but they used to call the little grassy space between the wall and the opening the “doorstep” in fun, remembering Bilbo’s words long ago at the unexpected party in his hobbit-hole, when he said they could sit on the doorstep till they thought of something. And sit and think they did, or wandered aimlessly about, and glummer and glummer they became.
Sorry, I don't know what PETE is.
