>>75190834You're right that incest does not automatically mean it's a crackship but most of the time it is because of how rare it is in Cannon stories.
Let's take the coffin of andy and leyley for example. Laylay very obviously has romantic and sexual feelings towards Andy so that doesn't require much thought on shipping her with her brother. But Andy does have quite a few hints that's pointing towards him at the very least having sexual feelings towards his sister even before the dream sequences.
The crackship in this story would be people shipping Andy with his mom. There's obvious story beats and evidence showing that the mother doesn't even love her son as a mother let alone as a lover. And when she assumes that her children are fucking each other she is seen with absolute disgust and dismay.
>>75190860You're right! This is a very good example of pro shipping. A general rule of thumb is anything that's considered taboo IRL is pro shipping in fiction.
