Also, please make sure that the ship pages are categorized correctly. If two character interact in one fandom, but do not interact in another, do not place that fandom on the ship page. It would not be a part of that fandom.
Having Canon and Fanon, with a couple of paragraphs, plus one link in the fandom section would be best. Obviously there are exceptions if the characters don't interact the Canon section would end up being a lot smaller, but we want those three sections filled out the most, plus some of the other sections if possible. You can see the Style Manual for those.
