Well I'm wondering what kind of language is used in statements about certain two parters, like the series 1 stories you mentioned, Rise of the Cybermen/Age of Steel, etc. all the way until The Rebel Flesh/The Almost People.

One thing that seems to be in common between all two-parters is a common cast. That is, most if not all of the guest stars for the first episode feature in the second, and also I don't think there's a single two-parters whose individual parts are directed by different directors.

This makes for an interesting case of Girl/Women, which only features one guest character in common (understandably so because the others are dead). Yes, different writers, yes not necessarily the same story, but it's definitely a narrative which continues on from the last one. Again, official statements should rule here. Are there any other prospective two parters written by different writers, by the way, or is this a one-time oddity?
