This is how Ratchet's Act of Kindness goes in Darkness Rising Part 5.
[Ratchet and Fluttershy sit together]
Fluttershy: Yes, Ratchet?
Ratchet: You know. I wish I was like you.
Fluttershy: Well, that's the nicest thing I have ever heard you say.
Ratchet: Well you're my favorite.
Fluttershy: And that is even nicer.
Ratchet: And I'm your favorite, right?
Fluttershy: Yeah. And you always will be.
Ratchet: And you'll always be my favorite.
[The Element of Kindness comes into view and a yellow aura appears around Ratchet]
