You have chosen for Finn to undo the effects of his previous wish. Finn wishes to go back to his normal life, to undo all the changes that his wish for strength brought.
Finn's wish is granted, and he finds himself back in his backyard, playing with his Hot Wheels cars. He is relieved to be back to normal, but at the same time, he feels a sense of regret for not being able to keep his strength. He starts to think about all the things he could have done with it, the good and the bad.
As the day comes to an end, Finn sits on his porch and watches the sunset, realizing that every choice has its own consequences, and he has to live with them. He starts to think about the Djinn, who is still trapped in the Hot Wheels car, and wonders if he should use his last wish to help him.
The choice is yours.
