I wonder what version number the place as it is now is.

It's not like they had a finished world to go off when they started. Mars'll be way easier.

Yup.

She sings some more songs. She seriously considers braiding some flower petals into Bella's hair. She doesn't do that. 

The plane lands in Toronto.

And witch-hunting.

The end of the world is merely the quiet terror of a half-city with only her original friend/victim ensconced in her at this point in the timeline. Bella de-witches her and explains the loose outline of the situation and plays through a post-witching therapeutic instance of the song and then regroups with Lúthien and - "Okay, remaining things to do before we go to your world are talk to both my parents and tell Raine she was important because I feel like she should know that."

"Yeah! And not to wish for that girl to like her...if I wish that I could transport people at will between places, even places in different dimensions, then we wouldn't have to take an airplane back..."

"This is true! And your distaste for planes might even actively help because you can work up strong emotion about not having to take plane trips! It would in fact be two of them because my mom lives in yet a third faraway corner of the continent."

"I really want to never need a plane again!"

"Do you think you'll get any more enthusiastic about that if we wait a bit or should I just hook you up with the wish thing now?"

"I can sing to get myself more enthusiastic - will my abilities be more powerful if I feel more strongly about them?"

"Yeah."

So she sings. The song is about departing Cuivienen. It's not a magic song but she doesn't need manufactured emotions for this.

I want to be able to go anywhere. I want to be able to take people anywhere. I want to go home, and go to Mars, and take Bella with me, as often as I want, forever.

And Bella takes out the wish granting thing and -

It barely feels like anything, except for the change of clothes and the sudden instinct for how to do magic -

"Eeeeee!!! I'm a puella magi!"

"Uh-huh!"

She has a longbow, too. "I'm still not going to be nearly as good as anyone at home, but it's pretty! And I can take us places. Any places, I think. Where do you want to go?"

"Charlie'll be fretting, let's go bother him."

She wants to be at Bella's house!

Here's Bella's house! Her dad isn't there but she can call him.

He comes home in pretty short order and receives hugs and explanations and a reintroduction to Lúthien.

"Hi! Nice to meet you for real!"

"...hi," says Charlie. "You two, uh...?"

"- it's complicated."

"I really like Bella but I don't have any intentions to marry her yet because of the species difference!"

"Whoa there, didn't say anything about getting married," says Charlie.

"That is one of the species differences!"
