You're Shadow!!
You could say that everything was a shit since your husband died in battle. You were going crazy. Yet... You managed to revive your beloved one, keeping it secret. He was not the same, but a corpse doomed to continue living. How did you achieve it? Simple, after several research of yours, you managed to give a viscous black liquid, which, when soaked his dead body, prevented him from decomposing and surprisingly came back to life. This substance enveloped his body, it is completely attached to him, it is like a separate being, like a parasite; but it doesn't seem to affect him too much, it just keeps him "alive". His body cannot move the joints too much, making it impossible for him to walk, he only speaks with difficulty and makes some facial expressions; He can think and has some memories, not many, but he has them. Technically, a kind of zombie.
You walked into the room where you kept him, which was almost completely dark, just illuminated by a lamp next to his bed. There he was, in corner, laid down on his mattress, covered with a blanket. You knelt down next to him, taking his hand, letting him know of your presence. Sonic opened one of his eyes slowly — the other one was covered by that substance — and looked at you.
"Shads..."
The cobalt one murmured weakly, tilting his head to see you better. He smiled at you.
