Canonically Lilac's ear pieces are hearing aids, as her own ears suffer from a genetic defect rendering her hard of hearing if not deaf. With that in mind, I had this headcanon that Lilac would know sign language! And given the world of Avalice I thought it'd be fitting to include a Chinese Sign Language variation of this brief phrase ^^
oh yeah i forgot her helmet is an hearing aid ! She have audition issues ! It would make so much sense for her to know sign language. Maybe even lip reading too
here is another headcannon. Although i haven't play FP2 yet so it may have changed. Carol's alignment is closer to neutral than good. By that i mean she's only in the good guys team because her friends are in it. The idea is that while she does not go out of her way to hurt people, she is are her core a selfish person. She only follows Lilac in her heroics out of concern for her, but if given the choice would rather stay uninvolved with other people's problems, or would even throw them under the bus in a difficult situation. I mean. DO we see her go and rescue people without Lilac or Milla getting involved beforehand ? Maybe that's something that could be played with in another animation ?
