Perhaps best place would be on Dougal's page under trivia? As far as The Fiery Cross's page goes the one conversation isn't exactly pivotal to the over all story arch. Maybe on Jamie's page since the conversation of him telling Claire is just between him and Claire.

Also the quote "Sister's son or no--I would that I had killed you, that day on the hill. For I knew from the beginning that it would be you or me." doesn't exactly say he hit him with the axe could have been the day he was shot in the arm and Dougal saved him from being skewered by the English dragoon. But it certainly does make it clear Dougal wishes he'd killed Jamie at some point.

I don't think it could refer to the day he was shot in the arm. That would have been Dougal choosing not to save Jamie. Dougal specifically talks about killing. Jamie himself seems to think that Dougal's words refer to the ax moment because him revealing the words to Claire start with them talking about hearing "no music but the sound of drums" since the ax attack.

I agree with you that it is not important for the story of The Fiery Cross, it is however very important for the Dougal/Jamie Relationship. I feel that putting it in Dougals trivia is too much of a spoiler for people (who haven't read this far yet or who just watch the tv series) who casually look at Dougal's page. Perhaps I will add a Dougal/Jamie relationship bit to Jamie's page..

Well I just said it could. It's open to interpretation because Dougal doesn't specify which moment. Because honestly he has had his chances to kill Jamie or let him die by not helping him.

Anyone casually reading any page on the wikia could easily find a spoiler because the wikia contains information all currently printed novels and novellas and the series is only filming season 3. You could add it as a relationship page and place it there. Could also give Dougal and Fiery Cross section as he is brought up during the novel. Between the last words, Jamie calling for his strength for the battle, heck Dougal is the inspiration of the fiery cross that Jamie makes. After all if characters like Roger's mother and the Reverend can get sections for novels they don't physically appear in why not Dougal.

Just to note a few things:

1) We don't have a strict spoiler policy on the wiki. The only unwritten guideline that I adhere to is that anything that has not yet happened on the show, should not be written on a show-only page.

With a series of books that has been progressing for 25 years, there's no possible way to cater to readers at varying stages of the book series, so book spoilers on book-related pages (including character pages) is completely acceptable and indeed commonplace here.

2) Another personal guideline: Putting information like Dougal's last words in either the Trivia or Relationships section is preferable to, say, putting something spoilery in the infobox, which is the first, and sometimes only, thing that a visitor reads. The further down the page, the less likely a casual visitor is to read it.

3) It's perfectly acceptable to add information to any article, even if you're not sure where to put it. If someone else thinks it would be better in a different section or page, they might just go ahead and move it. Still, if that happens, it doesn't mean you did anything wrong – short of obvious vandalism, every edit is a fair edit and open to discussion and further editing.
