Madoka Magica - 8

This episode had so many shocking moments!

Spoilers:

• Madoka was very close to becoming a puella magi, but Homura saved her again killing Kyubei
• Homura in tears :’(
• Kyubei reveals to have many bodies. Another of his bodies appears and eats his own corpse
• Sayaka becomes a witch
• Kyubei's full name is Incubator
• Homura is a time traveler
• Kyubei reveals his true purpose: to make girls into puella magi. Puella magi grow into witches.

So the source of witches are puella magi themselves and Kyubei feeds himself with grief seeds.
There are also familiars that turn into witches so maybe once a puella magi turns into a witch she starts spawning familiars.
The one who killed Mami evolved from a familiar, yet she left a grief seed... It could be that familiars are generated by the grief seeds recycled by Kyubei while puella magi turn directly into powerful witches and can then spawn grief seed-less familiars and witches.

By the way, the Mami-killer was trying to eat them, it makes me think of Kyouko but ok...

The references to Sayaka's outfit by the witch in the first episode were shown since long and have now much more foundation.

I liked a lot the detail of Sayaka's lifeless body thrown away like a ragdoll when she finally turns into a witch.

Things are probably going downhill from now. With only 4 episodes left there is some time to collect all the loose ends!
