Ever since that chapter came out, I've been wondering, “Does Giorno really have a palace?” and personally, I ended up with this “What If” scenario: what if it's actually Diavolo's palace?

In “Purple Haze Feedback,” we're told that when Giorno revealed himself as the Boss, he said he had always been the same person—not to mention that he killed Diavolo—and that the reason he had always been hiding was because he was a 15-year-old boy. Therefore, the prevailing belief among most of Passione would be that Giorno and Diavolo are the same person.

If that’s not how the metaverse works… But it’s an fanfic, so enjoy it.

Yeah, I don't like Megamind's analysis either, and there are some very questionable aspects to it, but Gru also has qualities that can counterbalance that.
