Don't want to rehash our whole discussion from a week or two ago, but looking at the game in a vacuum, I still don't see that as the inevitable path if you're committed to the throuple in a balanced manner.
That said, I still haven't played Acting Lessons but have had enough of the throuple path in that spoiled now to suspect DPC might have a wee bias against CNM. So definitely possible that'll influence things in BaDIK too. Interestingly enough though, JB and Elena is another form of CNM that was pretty much shown as the example of a happy committed relationship, so perhaps he intends a more balanced perspective.
