I don't ship Wincest, but I totally understand why people do ship Wincest. That said, I only get it when it's in the context of the show. Their lives are just so dark, and fucked up, and sad, and co-dependent, but the co-dependency is an incredibly natural product of their upbringing and is basically necessary to them. Like, they're not co-dependent just because. They're co-dependent because it's all they've ever known, and it's allowed them to survive. If you remove the context it's just like...wut?

So basically, yup, totally agree.
