This happened later in the night.
So Maura is actually a Magical Girl (TM), and Bass is her Magical Animal Guardian/Mentor (TM). The reason she’s driving a Prius in S2 is because she had her other car converted into the Bassmobile (which embarrasses him to no end because, really, how inaccurate, right?).
Jane is completely clueless, despite Maura conveniently “disappearing” during huge monster battles that the BPD can’t handle, and the fact that Magical Girl M fights in crazy tall strappy high heeled shoes and designer capes and whatnot. Bass just shakes his head and tries to hide as best he can in the Bass-O-Mati— er, Bassmobile.
