While Laplus, Kanade and half the police force were being retarded at the casino, Towa called Subaru to let her know that the gang is starting the airport heist soon. They said may the better children win and the loser is the worse parent.
But Subaru has dealt with her children for 4 days and they've made her want to put a bullet in her head. She knows the chances of victory are almost none, yet chooses to believe in them anyways. Truly the mother of the year. Good luck, Police Chief.
Edit: On second thought, Towa and Aki have already gotten captured. Maybe there's hope for this group of retards.
