She is in the cast list on here but I haven't seen anything mentioned about it. I loved her in Scream Queens and pretty much only seen SW:TFA because she was in it (with one line) but I still loved seeing her on screen and would like to see her in a slightly bigger role in this one.
Billie Lourd has disclosed earlier last year when she began work and promoting season 2 of Scream Queens as Chanel no.3 that she has returned as Lt.Connix in Star Wars EP VIII (8) in an expanded part from her one line extra bit in The Force Awakens.
What isn't known though is how expanded her role is and I don't imagine she has a major part but probably has a minor bit once again slightly more enlarged to that of a more supporting role.
Figure we will learn more later in the year given at this time she is grieving for the loss of her mother and grand mother.
Nothing is as it seems, nothing is just one thing and nothing is ever just over there;
I hope there is a season 3!! I'm not too confident it will get one though :( usually when a TV show gets its episode count lowered and the ratings are bad the show will come to a swift end. I also don't think the creators can be bothered with this show anymore either.
