Yeah, their date in MC room is optional. Maybe it's one of the options implying their solo paths later. Like, MC didn't help them a lot here and there, so they fall apart, etc. But it's still unknown, how DPC planned all this paths/sub-paths for the Throuple and Others (with feelings for Josy/Maya) branches. After EP8 it's more noticable that options for "help" them are only available in Others branch, since being in Throuple branch, MC always helps them. For now (EP9-11), the only options left for Throuple is a balance of solo scenes and ILY.
I think there will be same outcome available (solo path) via different ways. Like it was with Sage - become her boyfriend via fuck buddy or wait until she's officially "free" in EP7. Obtaining J/M solo path through "others" branch looks more polite and less brutal. While getting one of them via Throuple branch is more cruel and dramatic. That's why I'm still sure there will be an option to save the Throuple, otherwise all this balancing, RPs and other stuff are going to trash after so much years of development, which would be quite a nonsense.
