I think his "world went crazy" when his parents met Joe Chill in Finger Alley.

> > The key thing about Sam is that she's absorbing as much training from as many people as she can possibly get access to - the LL, Chaiki, Natalia, Champagne, even the Dark Knight when he was around. The end result is the Sam-from-the-future who guest-starred in UT #99-100. > I guess it wasn't clear then whether Sam had training from Chiaki or how much. Generally though, most of the people listed above teach skills. Chiaki would quite assertively point out that she teaches a lifestyle. But she would also note that her kind of training isn't for everyone, and would only teach Sam if she's willing to accept it and participate.

I don't know if Sam and Chiaki have met yet. Sam was mostly around during the Parody War, when Chiaki was off taking care of business (and avoiding the heavy government presence on the island). If they've met then Sam would certainly be eager to learn whatever Chiaki's offering.

> Though Sam might be interested if she knew that full Samurai training is nearly the same as training for Ninja.

She's probably aware of that from her training with Yuki.
