No, I think there are reasons to expect CS in this arc. Of course that fight I mentioned could be just a setup for another arc, but they were also placed on that cover where all the demons and fairies were, in sort of tiles, to some extent matching with opponents. So this is a suggestion by Mashima that they belong here. Of course he could change his mind or just placed them there for decor(though I don't really think he would do the latter), but if he did, that would be rather bad storytelling - promising something (or teasing, if you like) and not delivering.

Aside from that, insulting Juvia or Mira is bad thing and you shouldn't do that, kids ^^
