He's back. Back at the lab he was once experimented on. Mori his boss sent him here on a mission. He walks through the halls. Everything looks to be abandoned in a hurry. Everyone's gone. Except for one. He finds a child in a room, experimenting room. There's a dead body at their feet. They have blood and bits of brain all over them. They are crying and seem to be in shock. They are way too young to see this. They also look a bit like him. It's possible they could be his sibling?
