When the narrator gets back to the Brotherhood the Brothers all ask how it went and he said that the crowd was very moved, but that he went along with his "personal responsibility." The brothers are not too happy with this response, and wished he had put in more political things that would get the crowd riled up.
It is very interesting how the Brotherhood is so set on the narrator and all other Brothers essentially regurgitating what the Brotherhood has told them to say, rather than the speakers giving their own opinions. When the narrator gives a speech that is from his own experience and emotion, rather than what was written on a pamphlet, the crowd tends to get more out of the speech.
For example, when the couple is getting evicted and he gives the speech to the crowd, they starts a riot, while at some of his other speeches, like the "the Woman question" they seem to get excited, but without much outcome. When the narrator is transferred back to Harlem he is told to "keep them stirred up," and even mentions the eviction, while he then gives the narrator what to say.
