Question on Great Expectations

In Chapter 4, one of Mr. Wopsle's statements puzzled me greatly. It says that "'Swine,' pursued Mr. Wopsle, in his deepest voice, and pointing his fork at my blushes, as if he were mentioning my christian name; 'Swine were the companions of the prodigal. The gluttony of swine is put before us, as an example to the young.'" (Dickens, pg. 25)

Prodigal generally means gifted, or at the very least intelligent, yet Mr. Wopsle says the word as if it is a bad thing. Either he is saying that young men should be gluttonous, or his meaning of "prodigal" is entirely different from what I know the word as.

     Overall, my essay has not changed very much. I have modified some word choice issues, fixed some grammar, and rectified a bit of punctuation, but my concrete details and commentary remains the same. Assuming all of the others are also unchanged, we shouldn't have too much work to do on Monday.
     Do you think we need to fix up the conclusion? I checked over it again and it looks like it needs to flow a bit better, possibly by adding more transitions. Also, I'm not entirely sure whether one of my concrete details is correctly embedded, as I am unsure how to include dialogue from multiple characters when the source material is a script. Is it all right to just put a set of quotes around each and transition or does that count as two concrete details?

Thanks,
