OK, guys, I think I know WHO Howk 蛾 is. OK, this may not be true and I may be wrong but this is a 粉丝 fiction so.... on the 下一个 season, we'll see.. it will air on Netflix in December 2017.
OK, on episode 15, Howk 蛾 held a picture in a locket. It was was of Adrien's Mum! Now, I also seen other signs to lead to this person. In one episode ( sorry, 标题 unknown) this person looked at Ladybug 's earrings and asked where she got them. And also 说 to Adrian that he never had never seen the ring before.
