They could be.....

Maybe

No way, Max and Harper would be cuter. ^^

no not max and harper no beter with juliett

Yes! And here's how I would end the series, if I was writing it:

First, Justin wins the wizard competition and becomes a full wizard. However, Alex becomes a full wizard too as a residual effect from having won the premature competition in the Movie. Later, Justin finally falls for Harper, but instead of giving up his powers to marry a mortal, he flees with her into the past. This of course, is the real reason why the Future Harper (as seen in the Season 2 episode) is writing wizard stories in our time. Some fans speculate that the initials in her pen-name, H.J. Darling, stood for "Harper" & "Justin" and this theory fits nicely with my story idea.

I hope that someone involved in making the show reads this and makes this idea into reality.

Max And Harper <3
