Gigi fighting off the Red Devil in "Chainsaw," keeping herself alive through quick thinking and by taking advantage of her surroundings, finishing with a kick that sends him flying over the couch.
The Chanels deciding that they're tired of being objectified and delivering an epic beatdown to some douchebags in the cafeteria in "Haunted House." Chanel #5 actually breaks a lunch tray over the back of one of them.
Even if they are shorts, Chanel #3's big fat shut-up to both Chanel #5 and her boss, Chanel. All of this with a powerful monotone.
Dean Munsch revealing herself to be an Action Girl by single-handedly demolishing all three of the killers at the same time, sending them running.
Dean: When I was a junior, I spent a year abroad. I had an affair with a beautiful Eurasian man named Chon Wi Ha. He was a grand champion in the illegal Hong Kong fighting pits. Blood sport, they called it. I taught him everything I knew about making love. And in return, he taught me how to fight.

Chanel #3's Grim Reaper costume. There is even a glowing red-eyed raven standing on her shoulder.
Libby being a rather good sidekick after all by noticing a picture which refute Zayday's theory that Jane's child can only be white. Moreover she has speculated a good idea about Jane being a murderer after what we discovered in the episode.

Also, when Jane starts acting like a soon-to-be stepmother and insult her even if Sadie had brought her flowers. #3's answer roasted her more than Wes.
Chanel #3:I heard enough. I'm sorry your husband died and it made you sad. But can't you see the major logic fail in closing down a hospital that is actually curing people? Isn't that what you were so upset about in the first place? No one who worked at the hospital back then still works there. You're mad at architecture and geography. It would be like murdering all the guests at a Hilton hotel just because you got bummed out listening to Paris' awful song.
