Gloria Bainbridge was one of the significant high-ranked officials in Gotham City.
At night, Interim Mayor Holden Pritchard, Commissioner Reynolds, Archbishop McGregor, Gertrude Haverstock, and Gloria Bainbridge met at the Gotham City Hall to discuss the recent events involving the Legion of Horribles. However, Jerome Valeska and his allies went to the city hall where Mr. Freeze and Mad Hatter captured the mayor and the other members of Gotham's high society present. They took them to a van standing outside on the street, in which the other villains were waiting. Pritchard was still trying to convince Victor and Tetch to let them go, promising that he will double whatever they expect as ransom. Right then, the mayor saw Jerome Valeska standing in the van, who was scratched his nose unimpressed by these events and then smiled at the horrified mayor while Jervis handcuffed Holden to a metal rod. Upon noticing Valeska, Pritchard revealed that he has access to the police pension fund. Seemingly pensive, Jerome turned around and said "Wow, that could be a lot of money. Tempting, but, uh no, thanks.". Thereon, the mayor turned to Firefly who was standing next to Penguin a few steps away from Valeska. Pritchard said "Bridgit, isn't it? I can get you safe passage from the city, money, a new home...", but Firefly smiled and responded that it was people like him that locked her up in Indian Hill, and thanks to that, there is no Bridgit anymore. Pritchard immediately turned to Tetch and called him "son", promising that he can get him a pardon and that all will be forgiven, he just needs to stop this "lunatic". However, Hatter said that "lunatic" is a little harsh, he prefers "visionary".
The mayor then turned to Penguin, who was standing in the corner obviously not very happy about Jerome's plan. Pritchard asked Oswald if he can't do something, but Cobblepot put on a forced smile and said "Afraid not. I am with Mr. Valeska 100%.". As none of the villains were open for negotiations, Pritchard yelled that every cop in Gotham City will be looking for them, and when they find them, they should expect no mercy, just a hail of bullets. Jerome then started adjusting the mayor's tie and said "So serious. That's why your approval ratings are so low. Hey, tell you what. Try threatening me again, but this time, try it with a smile." When the mayor didn't start smiling, Valeska hugged Oswald with one arm and said "Aw, see, this is what's wrong. Nobody knows how to have fun anymore, right?", whereon Cobblepot nodded in agreement. However, Jerome then pointed at Scarecrow and said "But see our friend down there? Bag head? He's figured out a way to solve that.". Thereon, Crane came close to Gloria Bainbridge and used his laughing gas dispenser to spray the woman with the insanity toxin. While the gas showed his hideous effects by turning Bainbridge into a madly laughing clown, Jerome talked to the horrified members of Gotham's high society, telling them that it's time to give this city the boost it needs, time to stop taking ourselves so seriously. He then asked what Gotham has to lose, before looking at Gloria who was still laughing from the deadly gas, whereon he added "except your sanity". While Jerome bursted out into maniacal laughter to the delight of the other villains, Penguin seemed to be the only one who was disgusted by Jerome and his plan.
