Hmmm, well that's an issue, multiple factions could be after Shadow due to his status as the ultimate lifeforms, at least if they are aware of his existance, but nonetheless, does Ivo know of Shadow being his "cousin", you know, with everything about him tied to Maria.
[Sonic, Eggman, Rouge, Omega, and The Chaotix are in the living room of Eggman's flat in the nursing home together.]
“Yeah, he usually remembers. He remembers hearing about Shadow growing up, so that stuck with him.”
“Anyway, about the case. it's been two days now, and we've got nothin'. It's so weird! It's so unlike Shadow to go missin'... We've asked everyone, and nobody has seen him. A hedgehog like him stands out, with those bright red highlights! How has not ONE person seen the guy?”
“I haven't heard anything from Stone, either.”
“Yeah. He was supposed to come home to the flat after work two days ago, but he hasn't. We've been texting, though. Apparently the Mean Bean has been busy.”
“Funny. I walked past there earlier. It was shut.”
“Hey, it was shut yesterday too! I was gonna go grab a hot choccy, but it was closed!”
“You're getting hot choccies at your big age?”
“You're still collecting action figures at YOUR big age?”
“HEY, that's totally different, you—”
“HEY, back on topic, Dumb and Dumber! Do you think there could be a connection?”
"Did someone take my husband?!”
“Woah, woah, let's not jump to conclusions! You've been texting, haven't you?”
“Someone could have his phone!”
“Ooo! Has his texting style changed at all? Everyone texts in different ways, so... if he suddenly got worse or better grammar, or started using emojis he usually wouldn't, that's a sign!”
"Hey, you might be onto something, that IS a clear giveaway! I can always tell it's you when you borrow Espio's phone 'cuz there's suddenly a LOTTA emoji usage.”
“Hm... No, nothing unusual with his texts. They're still standard for him.”
“Well, it's still weird for 'em to both be gone at the same time. And why would Stone be lying? Did y'all have a lover's tiff or somethin'?”
“No! Not... That I remember. His texts are still sweet, there's no signs that I've upset him...”
“Aw, he texts you sweetly? Can I see?”
“Y'know, he did say something weird the other day. About curing Eggman.”
“THERE IS NO CURE FOR DEMENTIA. THAT IS A FOOLISH STATEMENT.”
“Well, I don't think it was about CURING, he just said I'd live.”
“No, I won't. Thanks for the reminder.”
“... He won't live. Unless...”
“Shadow... Why was he made again?”
“Uh- Part of an immortality project, right? To help Maria live longer 'cus she was terminally ill?”
“... Uh oh. I think I know who has Shadow.”
“STONE has Shadow. He's planning on using him to prolong Eggman's lifespan!”
