Honestly, that really broke my heart for Isaac's fans. I didn't even believe in the Grinch leak the same way a lot of other people did, just believing that we'd get Ken, Incineroar, and Shadow (ha... ha... weeps). That being said, when I saw that item, I really thought it was a GS reference, as well, and that it meant something. People have been wanting Isaac for as long as Geno, so that really tore my heart apart for them.
That being said, I realized something else that just makes me feel sick and I hope it isn't true. If on the very big off-chance, Erdrick doesn't pull through, that is going to sting. So many things are pointing for him, so I, as much as I support Geno and would rather the Square rep be him, am kinda... really rooting for Eddy now. I'd hate to see his fans get so close to the prize, only to get squashed. It's happened with the Chorus Kids, and in terms of perceived chances, it's happened to multiple other characters. Shadow the Hedgehog is the one that affected me, as I'm a massive Shadow/SA2 fan, and I was really sure that he was a lock. That feeling is awful.
I hope to goodness that this feeling doesn't strike Erdrick's fans, even if it means that a rep that I want, namely Geno, gets in. That's just not fair to them and it would just make me feel slimy. Erdrick, imo, really deserves this spot, and his fans deserve it, too. I don't want them to go through that pain people went through with Isaac, Shadow, and for differing reasons, Geno. It's awful.
