[Gameplay?] Bug regarding Darius' and God King Darius' lines in blind pick

The other day I was playing as Darius (jungle) with the "augmented Darius" skin. The ennemy team had "God king Darius" (top). When I casted E he would (sometimes?) play a voice line (The one I remember hearing the most is "Face me"). Base Darius does not have any lines for casting apprehend. I can only assume the reason he'd play those lines is because the ennemy had the legendary skin because i've never heard them in any other occasion. I remember that both God King skins came out with quite a few bugs. This one must have slipped through considering most game modes do not allow having multiple of the same champion.
