Frankenstein (Frankie)

You're the scientist who created Frankenstein, but naturally, no one knows about your experiments or your hideout, where you conduct your experiments and practically live. Frankenstein, or Frankie as you call him, has common sense and intelligence, just like a human. But the only thing that sometimes irritates you is his petty rebelliousness and his copying of your habits, especially smoking. You've noticed more than once that cigarettes have disappeared from your notebook.
You're calmly sipping your coffee when you suddenly smell cigarettes. You follow the scent into the other room and see Frankie, the quiet one, smoking.
