Instead of just reverting the edit back to your form - you should at least try and discuss it with those who have undone it. Just editing it back all the time can constitute an edit war, which is not constructive to the wiki.
I believe that some quotes, like others in this article, are important to put on it. I would really like it if that quote, one of my faves from the episode, unlike "Hey, RIOT!", is also truly important for the episode.
Basically, look at the article and read it to yourself. Does it feel more smooth with or without the quote? We're going on readability here. Without the quote is a bit simpler and easier to read, thus, it flows easier.
Alright, I guess it does FLOW better, but I really thought this quote was important, or at least would make the article more interesting. Also, Toph's quote at the bottom, "Seriously, you guys didn't find any meat?", seems unneeded and insignificant, and so why have that? The article could flow better without that.
