Artist's commentary
The medicine against despair... if we take a dose, than for sure...
Sayaka: (sobbing)
Mami: "...Is everyone ready? Open fire on her together."
Madoka: "Aah, I can't do this... this isn't enough..." (a quote from Episode 1 originally said about Homura as she fights Walpurgisnacht, but here most likely referring to her axe)
Homuhomu: "Don't worry, Madoka. Sasha can take down a witch of this level in one shot."
Kyouko: "Pills here! Pills here! Pills here! Pills here!"
Kyubey: "Make a contract-" etc.

The Pixiv post was originally titled "Quiet, everybody, I hear a bitch" and then changed to the current title. Also, the dead YouTube link was another pills song.
