Describe the final image of Chapter 15, regarding Mr. Brownlow and Mr. Grimwig

"The gas-lamps were lighted; Mrs. Bedwin was waiting anxiously at the open door; the servant had run up the street twenty times to see if there were any traces of Oliver; and still the two old gentlemen sat, perseveringly, in the dark parlour, with the watch between them."

They say quiet and almost hopeless, and yet they sat....... still waiting.

I might also describe it as "defeated."
