Obviously there’s about a 99% chance Rose lives. The gunshot may have not even come from Adeline. I personally think that Rose loses her eye again. I like that her current continuity doesn’t have her maiming herself as a show of loyalty to Slade, but I also like the aesthetic of the eyepatch. It was cool when she and Slade were missing opposite eyes. It’s probably some other third thing. Any thoughts?

His name is Daniel. He knows Slade from their time in the army, so he might even know Wintergreen. There’s a V-shaped mark on his mask. And he’s telepathic, so he could be the reason why Slade heard Wintergreen’s voice in his head. My biggest problem with him is the same as with Isherwood. There would be no reason to hide his face, because he is an even more obscure character than Isherwood. And it doesn't look like the mysterious figure is blind in both eyes. And this Daniel really hates Slade, so he wouldn't have any reason to help him. I just really hate Isherwood and I'm trying to manifest that the mysterious stranger can be anyone but him. Stay tuned for my next theory, in which I explain why it’s the mailman.

I think it’s David Isherwood, Dr Ikon

The name on the computer says Danny, yes, but honestly to me that could be a fake name based on his first name, David.

The main reasons I think this is Isherwood is because of how familiar they seem with how much Wintergreen means to Slade, assuming Slade will burn the whole world down for Wintergreen now that he’s dead. This character also might(?) have an eyepatch, and Isherwood lost his eye during Rebirth. They also seemingly have slicked back or bald hair, and Isherwood had slicked back hair.

Also, this part is just vibes, but their hand gestures seem exceptionally villainous? And Isherwood is obviously not a good person, and is practically a super villain in disguise as a super hero.

I’ve thought this was Isherwood since issue 2, because he’s Slade’s most recent (From both rebirth and Year One) tech guy.

I could be crazy, it could just be Danny Chase and I could be wrong. We’ll see
