 Madoka

The Homura = Madoka's mom theory has been around for maybe 4 episodes or so, but hasn't really been brought out as much as in this episode when Homura actually broke down into tears and threw out the stoic douchebag act. It mainly came from the fact that the two of them have the same eyes, and coupled in with Homura's time altering powers (altering her age so Madoka can't recognize her). I personally don't really think this will turn out to be true. Madoka was remembering something about her but pushed it aside, as if she didn't want to remember. But then again, it's hard to tell what this could be hinting to. It could mean that she's realizing it's her own mom, it could mean that she's remembering meeting the Homura of her own time line, it could mean that her memories are kind of merging with her alternate timeline self (in that case we'd have some Blick Winkle stuff going on, don't look that up if you plan on reading Ever17).

There was also the theory that Homura is actually Madoka from the future, kind of like Fate/Stay Night. This theory was first brought up by thew fact that in the promotional art, both Madoka and Homura use bows as their weapons. I think that'd be a funny idea considering Urobuchi wrote Fate/Zero.

And then of course there's Waluigi night, the night when Walmart opens up for all the witches to shop at, and we all know that anyone that shops at Walmart is evil. I'm guessing Kyubey is the manager of this Walmart that's opening up, and he plans on selling his harvested grief seeds to witches so they have extra lives! It's a complete win/win situation for him, the devilish bastard.

But really, next episode, I'm seriously expecting Kyouko to die trying to save Sayaka. Madoka will probably witness it because she'll probably meet Kyouko and they'll try discussing a way to make it work.

By the way, now that we know ALL Magic Girls are supposed to mature into witches, it's a good thing Mami died. She dies as a hero, and never has to deal with that downward spiral into absolute despair before breaking.

A bit off-topic but how would you react if this was Madoka's wish?

 Spoiler

Knowing Homura, she'll be put into a situation where she's forced to, whether she wants to or not, make this wish come true by her own actions in order to prevent Madoka from really making the wish.

And Kyubey and his master's reaction will be
