I'm starting to wonder, where did Grisha get his Titan shifting abilities? Yes I know he ate Frieda, so obviously he had those shifting abilities before. I'm also thinking what was he originally? Human or Titan? Maybe I need to review the past chapters or if I'm remembering correctly, that wasn't exactly clearly stated.
