It actually makes even less sense when you think about it: Telling Josy is objectively the wrong thing to do at the gym unless you're on the throuple path and plan to have no secrets from her. If you're on Sage's path you shouldn't be telling anyone before you tell Sage herself, on any other path it's not your place to tell anyone, this is objectively DPC's opinion as well because we see that from MC walking in on Matthew and Olivia at Halloween, you can only tell Jill if you're on her path because it's her best friend being cheated on and you shouldn't have secrets from Jill, on any other path MC states that it's not his place to say anything. Yet if you do the right thing and don't tell Josy then you are punished in ep 10 because having Sage at the house helps you with Patrick.
