Alone

"As he went forward it grew and grew, till there was no doubt about it. It was a red light getting steadily redder and redder. It was at this point that Bilbo stopped. Going on from there was the bravest thing he ever did. The tremendous things that happened afterward were as nothing compared to it. He fought the real battle in the tunnel alone, before he ever saw the vast danger that lay in wait." - JRR Tolkien, The Hobbit
