She was sitting listening to something on her phone when she started to fall asleep then Nick calls. Sudden loud noises while on the cusp of sleep is jarring on the nerves and can cause someone to jump startled and the earbuds in her ears directed he ringtone into her ears. I suppose I could of just said that Nick called her just as she was falling asleep and the ringtone was directed into her ears thanks to her earbuds.
@Cyber Security. "Many people ask if this comic is going to be a romantic drama. (I cry) Everything up to now was just a prologue to show that Nick and Judy are now closer (to the point of dating) 7 months after the nighthowler incident. We, GlumHum and Xzylo, are looking forward to bring you the next chapters; where we will be introducing you, the readers, to the darker side of Zootopia; and the main story of this comic. Yes, the genre of this comic is going to be Crime/Drama
Can’t wait to show you a new threat that will be coming to Zootopia soon…"
