They make a plan for revenge

Barbara and Kara follow Lisa to her home, which wasn't very far from the Gotham Park. They each did their best to cover their embarrassing panties and bras they were wearing. The panties were pretty stretched too from the wedgies Amy gave them and from when they were tied together. Lisa didn't bother to ask what happened, she's been the victim of Amy for a while now, but in her mind she was shocked that Barbara Gordon, daughter of the Police Commissioner and first in her class would be wearing such childish panties. Once inside Lisa's apartment, Barbara and Kara were given spare gym shorts and Tshirts. They gladly put them on for cover. They both realized that Lisa was significantly smaller then them and didn't have an athletic bottom, because both Kara and Barbara's gym shorts were really tight and a bit cheeky and if you looked hard enough you could see their panty lines. But the girls were grateful nevertheless. They thanked Lisa and said goodbye. Barbara didn't want to have to face Lisa for fear of any questioning.

Once out on the street again the girls walked shoulder to shoulder and talked about how tonight, they should go out together and find Catwoman or Harley Quinn and get some good old fashioned revenge. Unknown to them, Catwoman and Harley were walking right behind them in normal clothes and overheard their plans. They watched as Barbara and Kara went into Barbara's apartment and then the 2 villains began to make a plan of their own. Catwoman knows that if Batgirl is really angry, she is difficult to handle, plus if Supergirl gets even a hint of her powers back this could be bad. Then Harley brought up a great point, "Well Kitty cat, Lets get the advantage then! 3 vs 2! Lets get the Gotham City Sirens back together!!" Catwoman grinned and agreed, "Harley dear, make the call."
