I really don't get why you think that there being no confrontation or Josy being able to hide away from the confrontation would "destroy the cliffhanger". Cliffhangers don't need to be resolved in the way you expect them to, they're sometimes just meant to tease the possibility of something happening later or to make you think something big is going to happen but ultimately resolve it quite easily and with less fuss than first thought.
It's like if an episode of a TV show ends with a bomb that's about to explode and kill one of the main cast members; you might expect it to blow up because that's what bombs are designed to do and that's what it appears is going to happen, but what's more likely to happen is that the bomb will either be defused by somebody else, or the character will manage to escape it, or it will be a dud, and this will happen in the first 5-10 minutes of the next episode. The rest of the episode, or even season, will then be focused on finding the person responsible.
This doesn't "destroy the cliffhanger" because the cliffhanger doesn't always have to have a straightforward and obvious resolution in the next episode. 'Lost' was a show that frequently ended on cliffhangers and teasing endings that weren't addressed in the very next episode, but were just meant to build towards future events. If Maya's Dad isn't there when they get back it builds tension for later because you never know when he'll return, or if he is there and Josy can avoid being seen by him then this at least gives some resolution to the cliffhanger but still keeps his imposing presence in place in order to be the key source of problems for the M&J relationship drama.
I try to explain myself better.
seeing Maya's father waiting for the two girls in the room represents a great danger, an unexpected danger in that form, one thing was the pressure he could put on Maya, one thing is the danger of his physical and unexpected presence at that moment.
if the girls avoid him, realizing however that he can enter their room, they completely cancel this danger. the pressure remains, but that was there before.
Josy should have lived elsewhere before, they talked about it as soon as she gets to BR and then they ignore it for a week.
therefore all the new dynamics, if any, of Maya and Josy moving away we could have lived without the need for a night visit from Maya's father.
in this sense the cliffhanger is completely canceled, it would not bring any effect that should not have arrived the same. this is the definition of useless
