You Come Here And Expect Me To Be Believe Your My Mum And Dad! (Harry Potter)

When Harry finds his parents and others stuck in his world from another dimension with no magic, where they're seperated, and have another kid, on his 18th Halloween.

He has to either trust them and let them into his world, and teach them magic and their love again, or help them get back into their own world.

Which One Will He Pick??
