The short one, the one about his job, and the one not spoken about him.
Of those three, the first and third are preferable since they actually give insight on Kristoff as an individual. Even if the first one is short, it's better than the second because in the context given, it's clear that it shows Kristoff as a selfless person who cares about his friends. Also, unless there's some clear statement that a quote must be said by the subject, I don't see why we can't use the third quote.
The problem with the short quote is that it is not very memorable. That, and the fact that it seems too short; I think the quote could use improvement. The short quote, while indeed reveals an aspect of Kristoff's character, does not reveal enough. Now, the longer quote does better suit his article, as it reveals more about his character than the short quote does. I think the quote should reveal more about the character's personality, like the current quote does. I don't know if there's an issue with the length of the current quote, but there seems to be no specific rules about the context of the quotes. This also means that there is no limit to who is able to say the quote.
While I believe that the current quote better suits his article, I think that the second one fits as well. Sure, it may not reveal much about Kristoff's character, but it reveals more about his profession and is somewhat memorable. Like I said, there are no rules in regards to this issue, so I don't know the limits on the use of character quotes.
I agree that it wasn't memorable, which is why I replaced it with the Fixer Upper line. The only issue seemed to be that Kristoff didn't say it, but it seems you've moved past that.
The second one does fit, but unless there's no other alternative, it's best to have a quote that captures the essence of a character. Kristoff's job description is covered by the introduction where it says he's a Sami ice harvester.
Well, there still is an issue with him not saying the current quote. But like I said, there are yet to be any rules that specify what should be said in a character's quote box. However, I'd like to see what everybody else thinks about this...
Well, since the quote belongs on the character's page, I just thought that the quote should be said by the character, as we are in their article. It's not that there is something wrong with not having Kristoff say the quote, it's just that the idea of the quote belonging to Kristoff himself seems more compelling, I guess.
I see what you mean but I think the quote's contents should be judged more than who said it. It's a nice bonus having the character say it, but between a quote about selling ice and Kristoff's personality, the only benefit of the former is that Kristoff said it.
