The same way you can point out the same relationship between any pairing people think/assume are romantically involved, show how funny and/or gross they find the idea that they could ever be more than friends. Someone suggesting that they're together gets a laugh until they realise the person is serious at which point the outrage and disgust set in. This works even better for characters who are related but it works well enough for any pairing that aren't a couple. _[Supernatural](https://en.wikipedia.org/wiki/Supernatural_(U.S._TV_series))_ does this very well, repeatedly, with the Winchesters, as does the [Emberverse](https://en.wikipedia.org/wiki/The_Emberverse_series) in which it is applied to a number of both same sex and mixed gender pairs at different times.
