It's important to be clear what we are talking about. This whole thing started when some people talked about threesomes and there are indeed quite a few, also for finished routes, which can just be added, without any extension whatsoever, like some of the ones already named. These things have happened they'll almost certainly happen again.
Then again, it's also true that there won't be any actual story additions beyond these things to Jenny and Eve, which are actually the only character branches that are offically finished, everybody else still has at least one bar left.
In the end the discussion won't lead anywhere for now, but Sploosh for example pretty much said that he wants Tony/Maria and Eve/Odette to happen, so it just doesn't make that much sense to claim it's impossible because of formalities. That's the good/bad thing about indie development, they don't really matter and can be changed at will, as it has happened quite a few times in these last years.
As said, I think that's too much. Keep in mind that you'd have to explain the whole trans/body issue stuff, etc.
The best hopes I do have for Eve, next to the dating/prom, would indeed be an Odette threesome and hopefully a few more solo scenes.
That's going to be Becca's room for the next update.
