I am confused in season 2 episode 16 future Harper. Harper say's 'has mason broken up with anda yet'(to Alex). Does that mean they are going to break up for good ??? (hope not)

Well, they did break up just as future Harper said, but that doesn't mean they don't make up. She might've been saying that so if he did, she could reassure that they'd get back together. Maybe.

no no no i think future harper berkata have u met mason yet. they might break up. find out on friday 8:00 june 24

Yes they do. Then Alex and Justin finally admit they're toarally in love, change their names and pindah somewhere. Then they all live happily ever after. Except for mason who got ate oleh something even bigger than him.

Ok enough of my fantasies. Based on the end of the most baru saja episode, they probably will end up back together.
Future Harper DID ask have anda broken up with him yet though, so she could pindah on to someone else. But this is disney were talking about. So future harper saying that probably means nothing now. Plus, the future can change rather easily.

no cuse wen they make episode that usally link 2 a future episode wat was berkata wont happen alex and mason r still 2gether even though they took a little break 4 now

They have broke up a lot of times but they will proally will make up again
