Maybe Pegs is a remnant of every day life. Often our fellow man can be found annoying and useless at times and shot the dirty look whenever their actions, however good intentioned they are, accidentally cause more havoc than expected.
Everyone wants to be the hero of the story, but realistically sometimes there are people who are just surviving and completing the layering of what society once encompassed.

Actually story-wise, I think Pegs rises up when the occasion calls, but her clumsy actions and words imprint deeply in the listeners' mind.
I know I remember the times I screwed up more over small achievements.
