She's lovely and could do well. However, will she be a Jubilee that plays an active role in the plot or more background? I doubt she'd be as extra, as she's appeared in all the other films; but she could easily turn out to be a Blink in the DoFP movie.
Not that I really like that they're mixing up the generational age of the character. I still haven't watched FIRST CLASS, because of what they did with Emma.
