This is when Carver is helping Bowser and the villains in Destiny Hearts.
(We cut to Bowser, Kurumu, and Carver)
Kurumu Kurono: (sighs) You know that sharp knives for brains could've had them..... If someone had stuck around and give him a hand.
Carver Descartes: Hey I'd did my part. I'd brought the princess didn't I?
Bowser: Shredder was beyond help, consuming of his hatred for the Turtles. But he did let it burn to fiercely.
Kurumu Kurono: Whoa, whoa, whoa. Lighten up will ya! I'm cool as a ice cube when Tsukune will be all mine. By the way, Carv, why we got something special for you.
Carver Descartes: Uhm?
Bowser: We had a deal, yes? You help us and we grant you wish.
(the glow shows Lor and Tish)
Carver Descartes: Tish, Lor!
Bowser: Go to them. Your vessel is waiting.
(Grizzle walks up toward Carver)
Grizzle: Just remember, this ain't no pleasure cruise. It won't be a pleasant voyage.
Carver Descartes: Why are you doing all this for me? What's the catch?!
Bowser: Catch? "What's the catch?" Silly boy, you're like a nephew to me. I only wanted you to be happy.
Carver Descartes: (pushes his hand away) I seriously doubt that.
Bowser: Believe what you wish. But least we forget, I've kept my end of the bargin.
(Then Carver turns around and walks toward the hall where Grizzle is as, Bowser is watching him walk)
