There's no harm keeping the section as it is than keep edit warring. This wiki is more lenient on trivia. Some character trivia is very trivial already (Woodie's allergies? Yup), so speculation about Wolfgang's past/nationality/etc. is fine, something something grandfather clause. Seems there's argument about his cold preferences, too? A confused player might wonder if it's true and look to the page for information, so I'd keep it.
However, if you actually know that it's speculation, then it must be noted as speculation, such as replacing "suggesting that" with "it could be speculated that". Wikis don't consider speculations as factual information, do they?
It might be in your best intrest to know that someone added an inappropiate image to the wikia. I seen it in the "Recent photos on this wiki" section. It features game characters, Wilson and Willow having sexual intercourse.
Just so you know, I've adding a new category and template for images of low quality. If you see one that you feel needs to be updated go on ahead. Also, going into recent changes, you should a new bar of things that can be done.
