Well, it could well happen, although could also happen something with Lucy (for the ones that did not have yet had that, because they had the dinner, would be even nicer), or maybe, both, depending on the player choices.
If I was to bet, I would bet that, other the one you mentioned, over the next updates (notice, "updates", not "update") we are going to get something with the two cops (if it does not happen in the next update), something with William (since he will temporarily move in with Myriam and Katherine), something with Lucy (since Myriam is now frequenting her more) and maybe at least one of the possible volunteering options, something with Cassius (well, since now he feels he is "the male of the house" and sleeps in Myriams' room pretty much every night), if you did not close that route.
Maybe another interaction with the priest, if one did not close that route. There could be already enough for a few updates, without forgetting the kids, Charles, the students, the metro, the modelling, the suitcase.
I guess also that in few updates (the time to get to the week-end, that why I say "in a few updates") there will be again something with Marc, since he said he will go back in the week-end to the pool with his team mates - though hopefully Zorlun will not try to use that to "kill" Marc (otherwise, the incest patch is for nothing
). Maybe we could even get something with Katherine, of course not sexual activity with Myriam (that is out of the question), although that wpuld not automatically exclude Katherine seeing Myriam in some activity.
If I remember well, Zorlun excluded that Katherine would ever be involved in any sexual activity of any type, but I may be wrong, I am only sure he excluded Cassius, Myriam and Marc as partners for her.
Of course though, the ones above are just my speculations, just for fun
