Y will effectively have Ilde and The Darkling help her jump a Public Security droid. She'll access the android's basic systems and do a quick hackjob to modify its programming. The android will then arrest all three of them, process them and accompany them on the train into the jail. They'll be able to take any belongings that they can conceal in their regulation jumpsuits, but all other personal belongings should be left behind somewhere safe - hopefully you don't like the clothes you're wearing right now, but you're probably not getting them back. WHOOPS. Enjoy your jail jumpsuits, everyone.
