It still isn't tied to KKR. It is tied to early days DK, which now nobody looks at.
Those Oil Drums have as much connections to DK as they have with Hogan Alley or that Game & Watch game called Oil Panic. Should we expect a Ms. Game & Watch as an echo now?
I swear people are going nuts over these false hints and Illuminati crazy theories.
If I may.
Was Robin's missing Final Smash evidence Chrom was in? No. Lots of characters didn't get their Final Smashes shown. Like over a dozen.
Was Ike's missing Chrom palette evidence Chrom was in? No. Lots of characters have missing palettes, even some fan favorite ones, like Fire Mario, and Ike has an excuse of a second costume.
But taken together? Then it begins to paint a picture.
Same with Dark Samus. Was her missing AT evidence? No. We're still missing a bunch of ATs. Some are probably legitimately just cut.
Was Samus losing her palette evidence? No. Same reasons as Chrom.
Any individual clue can seem innocuous when on its own. We can find plenty of explanations for all the individual elements in that room being there, and I'm still not suggesting the chair room means anything. If an oil drum isn't suspicious on its own, and a rope ladder isn't suspicious on its own, when you put them together, right next to each other, that's what makes them suspicious.
