Julia/Jillian
Julia did not respond to the -uppity light worm- other magical girl. Rather, she hovered there in silence. It took a few moments for her gaze to finally migrate away from the girl, and onto the beast that was nearby. It was clearly not natural, and Julia had some guesses as to the nature of the creature, judging by the feeling of its mind and magic. She did not move her eyes until the beast left. Once it was out of sight, she instead closed them, following it mentally for as long as she could reach.
In the end, it was Jillian that spoke first out of the two of them. Julia's other self floated forward, gesturing towards the magical girl whose presence Julia had felt before they were attacked. "You fired upon us," the obviously ghostly girl announced, her face set in a frown, "If we're not mistaken." There were few easier ways to anger Jillian than threatening Julia's safety. Despite the situation, the silent girl's lips quirked up in a smile. Her eyes opened to focus upon the offending girl.
"We demand an apology or recompense for this hostility." The time for niceties was before one had been fired upon.
