I had a theory when I was rewatching the movie for the nth time now...

The scene after the party stuff. When Bear comes home with Nikki and they talk about space and Nikki throws that childlike tantrum... and they talk.

Wish Nikki says something that I don't think I've heard many people talk about... and that is this dialogue right here...

Bear says "It's not real"

Nikki says "I love you in every reality"

Do you think the OWW works and alters Nikki in every reality? or we don't go multiversal?

I've had that doubt since I heard the movie and waited for someone online to post or talk about it... but I haven't seen any posts so I thought I should just ask if there was any confirmation or denial about this...

Because this opens an infinite amount of possibilities of the stories... 

for example: a reality where Bear actually told Nikki his feelings to which she probably denied because Nikki considers him a brother of sorts... and the wish willow snapped (in our reality) made her the same Wish Nikki went see... and She creates chaos here...

or a reality where Nikki and Bear are actually dating and the willow snap affected this Nikki and creating chaos here as well...

My imagination stretches a lot further than I would like to admit or even think about...

TLDR; Wish Nikki said I love you in every reality... so does the One Wish Willow work in every reality or was it this one alone?

I have a question. A big one (for me)
