Ask yourself this, when has anything good come from a child taking a liking to a ventriloquist dummy? When has anything good come from that kid whose into ventriloquist dummies, having access to weed killer and a punch bowl at the birthday party of a girl who makes fun of her? Never. The answer to both those questions is never. That was nine years ago in young Shauna's life.
Flash forward to present day and Babs shows up in tears to her psychiatrist's office. Babs has had a rough couple of days, noted by her shrink who smells a bit of alcohol on her. Babs begins to describe the last few days (following her brother's "death" and with a lack of some batty details) which begins with Babs making some alterations to her "volunteer" uniform, removing her chest emblem, before heading out on patrol to hopefully clear her mind.
Elsewhere in Gotham, the not America's Got Talent auditions are happening, and wouldn't you know it, Shauna the Ventriloquist, looking creepier than ever, shows up with her dummy. Long story short, she gets berated by not-Simon, and gets all crazy, and ends up using her dummy Fredie to kill not-Simon, while exhibiting some TK like powers. Shauna takes blonde not-the typical "honey, you're nice I love your energy but no" judge hostage, brings her outside, throws the judge's voice to get everyone to storm into the auditions, then brings her hostage into a nearby parking lot, which is the point Babs gives chase.
Being that the parking lot is in Knightfall's building, we see her order her two associates to check in on the commotion, while we also see Ricky off in his apartment with a new fake leg, and something about his brother making a move on some open turf, or something.
Babs confronts Shauna, throwing a batarang at the ventriloquist, only to have it stop mid air, and fly back at her, hitting her int he head. Then, surprisingly enough, without Shauna's help, Fredie flies at Batgirl, having a new found morbid attraction to her. Babs even struggles to fight him off, but some rent-a-cops show up, Shauna tricks them into thinking the judge said Batgirl abducted her, which leaves Babs to deal with them, while the real kidnappers escape.
Back to the shrink office, Babs seems to confirm she's all distraught because she got in a fight on purpose, or something, then remembers some licensee plate numbers, meanwhile Shauna has the judge tied up with her dead parents, and Commissioner Gordon finds out the police can't find his son's body, and proclaims a vendetta against Batgirl. Yeah... I wanted to wrap this one up.
