Personally, I find the whole "narratively ambiguous" label to be total garbage. People either are or they are not a companion. There's no in-between or middle ground. The tricky part here is that the episode itself leaves the question open-ended. Of course, the fact that there isn't really any definition of a companion doesn't help. I would say just leave them off the template unless Moffat or a BTS source confirms their status one way or the other.
