Speaking of Chapter 1, do you know when the many revisions finally stopped (for now)? When 14.5 dropped. There were even TWO versions of 14.5 with the first version quickly revised. But DMD has been saying this and doing that from the beginning (a work-in-progress, indeed!). Also remember, even IF the Elena cliff hanger remains as is during 0.19, there are several outcomes to that scene. One possible outcome is Elena becomes an even more trusted confidante than she already is (I only play a D-only path where both F and D have rejected Elena). The testimony of an unofficial dev-teamer,
@Jeff Steel, that Elena will be pivotal in 0.19 is the single largest piece of info DMD fans have so far to indirectly make sense of the cliff hanger.
Sure, Elena and many other DMD characters will learn of the F/D relationship. But how and when is very much up in the air.
