The title pretty much says it all. If Lilly makes it to the TWD TV show, which of course may not happen, who would you like to play her character. Name actresses that might fit her character. Provide links for photos, names of movies the actress plays similar roles and whatever you like :) You can even vote for the best choices if you want.
The first to come to my mind would be Eva Green.
I think she even looks a bit like her version in the game.
Eva Green plays Morgan Le Fay in the now canceled TV show Camelot.
