Ive thought about this for awhile, but I'm kinda dissapointed that Risa never uses "father" or "mother" when talking to Gil or Shia. I know in her head she aready has\had (seeing she cant go back) parents, but its been over three years now since they adopted her, and considering all the support, both financially and emotionally theyve given her, it might be nice if she called them that.
