Well, my opinion at first glance, that not going to happen. If they decide to, I think that Fake Tears and Flatter could be the propers. In the Dark-type side, Fake Tears recall that unreal way to get something. On the other hand, can resemble that fairy innocence that serve as vehicle to achieve a purpose. Under the Dark-type, Flatter can seem as an unreal act to make someone proud of something. The fairies can do the same act in a real way trying to make the target happy. The first one is unexpected and unreal; the second is real, but it keeps you thinking about what could happen next. Just like receiving candies from someone, the intentions can be real, but the act confuse.
