Conversations.

Overheard conversation between Emma and Tripp while they were playing Rabids on the Wii....

Emma: Try your best. Believe in yourself. Put your mind into it. You can do anything you put your mind to.

Tripp: I can't do it like you. You put your mind to everything.

Tripp still loses. Emma wins.

The next game starts -

Tripp: I am putting my mind to this game.
Emma: Believe in your heart. Believe.
