Nah. That's just an initial arc to bring Yuna into the story. I reckon that'll be resolved in short order, not least because how can Carol lead the Avengers when she can only be out for a few minutes before she automatically gets swapped with Yuna? Last thing they need is for her to be in mid air trying to fight an enemy, and suddenly she gets replaced by a teenage girl who can't fly. She'd be a liability.
