Okay but

Why do so many people think that Wammy's House is such a... dark place?

Like, a lot of fans make it out to be this dark place where all these children grow up believing their only purpose is to be L's successor. And all these kids ever do is solve cases.

Yes, you here from Near that he's solved some cases that L has sent his way in the L Change The WorLd novel, but he sounded rather fine and even happy to be working on cases.

The only ones who were in line to success him where A, and BB and after them, Mello and Near. The others just did what they could to help out

Plus the little scenes you see from it are with normal, happy kids, being kids.
