I have to say this was one of the first stories Mulder/Krycek I've read... Earlier I've read Krycek/Mulder and switch roles was hard to imagine for me.

Huh. Interesting. Now there's a concept that we don't have in het. I suppose psychologically you could point to stories that were Mulder/Scully or Scully/Mulder, in terms of who was more forward in the relationship or whatever, but it just isn't discussed that way. Different languages.
