Oh, no, it's fine. Part of me LOVES the fics in which they settle down together in a totally gen way too. It's just that a part of me also wants them to maybe figure out how to live as fully realized individuals as well. I don't know. I'm not exactly rational on this topic. ;)

Most of my favourite curtain!fics involve Sam and Dean settling down together in a perfectly cozy domestic setting with no romance whatsoever. So, for all I know, Fusion will probably end up that way as well.
