After seeing Crisis on Earth-X, some girl appeared at Barry's wedding.

All say she's Dawn Allen. Is that really her? If so, why is she here? Will we see more of her this season?

Perhaps she's come to warn them of a danger yet to come. Possibly also to help them stop the Thinker and keeping the Flash family legacy alive.
