The changeover is made - the 'Alternative' version has replaced the original version of chapter 14 in the mainstream tale, and chapter 15 continues on from there. Chapter 15 depends on and carries on from the activity and happenings in the 'Alternative'. Thanks to all who gave me their opinion, and apologies to those who preferred the shorter version, but the vote really was overwhelmingly in favor of the longer (Alternative) version (the one with Ruth participating).
I wrote two versions of Chapter 14, because, sleeping on it, the next day I felt a little doubtful about one scene in the original. So I wrote a new version, leaving out the content I was iffy about; published the 'iffy' original as an alternative version (as a separate submission, not in the main "Relaxing Assistance' story), with the de-iffyfied version in the mainstream tale. So far, two days later, the overwhelming weight of opinion seems to be in favour of the original (published as the Alternative) version. So - if you have a view, please express it soon. At the moment, it looks like I'll change things soon so that the original goes into the mainstream...
