"Well, it was a stupid one!!!"

Here, have a fun phone sketch I whipped up when at work with an idea I've been playing around with for a while- what if Heisenberg made Emelia a replacement eye? //Not too fond of how he looks when done on my phone, but I'll do him justice soon enough 😂 He's fun to draw anyway, ofc there'll be more.//
He'd make it gold instead of red to match her other eye, both so its even and because everything in the factory that glows is red- it would be a small reminder that she might be a little more important to him than she thinks. 😏

The eye would /somehow/ also be attuned to her mutation, making it easier for her to manuver and use, and make it so the mutation wouldn't straight up destroy it (he made sure of that). It wouldn't really change the mutation much since its not a device like those on the other creatures in the factory, but the mutation might make it... 'stronger'? The 'vision', at least. Like, maybe allowing her hawk sight with that eye.
Like his metal leg(my headcanon, of course), it would be fixed to the bone of her skull via thick bolts infused with the cells, in which YES, Emmy, it'll be painful. Thankfully he'd put her under and knock her the fuck out first. He's good with torture, but he's not THAT bad, especially with her. He'd be at least a little merciful. Maybe he might even let Moreau help... The guy probably has some anesthetic somewhere in that clinic of his. Plus the healing process would be absolute hell, but at least he's smart enough to know how to avoid the obvious issue which would be brain damage, and its to the point where she could probably smash her head against something and there wouldn't be an issue.

Also the visual of her mutated and leading the Soldat army with a single golden glow amongst a sea of red is slightly nightmarish from what I see in my head, but have the simple sketch for now. 😌 I MIIIIIGHT do a thing for it though... Its nightmarish, but fucking awesome.

I dont THINK this is Canon for her. Not yet, at least. Not too sure about it... 🤔
