How did April meet jack in scarper jack?

It seems you're asking about the character April and Jack from a fictional work, but you haven't provided the context of "Scarper Jack."

Could you please clarify:

* What is "Scarper Jack"? Is it a book, a movie, a TV show, or something else?

* What is the full title of the work?

Once I know this information, I can help you understand how April and Jack meet in the story.
