Why Justin from wizards of Waverly place keep seeing Juliet?

There seems to be a misunderstanding. Justin Russo from "Wizards of Waverly Place" doesn't see Juliet in the show. Juliet is not a character in the series.

It's possible you're thinking of:

* Theresa: Theresa is a character in the show who is a recurring love interest for Justin.

* The "Juliet" you mentioned might be from a different show or fanfiction.

Could you please clarify who you're referring to? I'm happy to help if you provide more details.
