Saying that it was too late for her to be convincing at this stage, Homura simply leaves them alone. Madoka and Sayaka began to witness first-hand witch fighting. Sayaka bringing a bat was natural; Madoka drawing her clothes were cute. Mami begins her fight with the witch, an odd-looking creature, and efeats it with her rifles. While Sayaka continues to dislike Homura, Madoka cannot help but feel that something is odd about all of this, yet shrugs it off.

Speculation:

I can't help but think that there is an even bidder price to pay other than just risking one's life when becoming a magic girl. That grief seed that Mami collects after her fight with the witch, I cannot help but think that it is just another Soul Gem but overcome with darkness. In fact, the fact that the Soul gem releasing its darkness and passes it onto the already tainted gem heightens my fear. The balance between witches and magic girls...could it be that the girls are the witches once their soul gem "dims" into a Grief Seed?

And of course in Mandarin and Japanese Mahou Shoujou (magical girl) grown up term is Majou (magical women - witch)
