Well. Nova Pandora is right-- Natalia is, indeed, getting into Lucky Stars via the back-- specifically, via a way that she'd discovered Kalim had used to haul in the parts for a whole-ass sectional couch.

It did, however, demand she know her way around a lock.

Or, perhaps, more accurately, know her way around a door shim. How in the world a high schooler got her hands on a steel door shim is a question she's not going to answer and it's not really what Pandora wants to know, now, is it?
