Kori has to stop mid-air when her phone rings to answer it, and unfasten the friction-guarded pouch she has secured to the side of her costume to take it out. "Hello?"

Hovering, she's a single bright spot in the Gotham skyline, and something of an easy target, so she lands on a rooftop for the duration of her phone call, checking to make sure she's alone. She will hand it to the vigilante crowd, the rooftops do give one excellent cell reception, almost as good as the sky itself.
