This episode really put Kyouko is a better light. You can understand why she acts how she is. She made her wish to save her father as he was hitting rock bottom. You look at Madoka's loving family, and you can understand why Kyouko made that her wish. (Obviously they didn't know each other back then.) The sacrifice in being a magical girl was well worth it for Kyouko. But the one she made the wish turned on her, and now she is broke and alone. You can sympathize with Kyouko here because helping those she cared about backfired on her. Now as a magical girl, what's the point of hunting familiars if it means expelling her magical energy and not getting anything out of it. Her kindness backfired, and it is hard for her to get past that kind of trauma.
Honestly, I am more impressed that it was Kyouko that did what Madoka would have wanted. She empathized with Sayaka and tried to be on the same wavelength, but here Sayaka pushed her away. Kind of the point where her ideals are overtaking her actions. Yes, being a magical girl gives one the ability to do tons of good, but what about Sayaka's happiness? I guess for Sayaka she truly hasn't hit the bottom that Kyouko has and can't understand what Kyouko is trying to do here.
At this point, Kyuubey really showing up as a creep. It's pressing on Sayaka's Soul Gem is basically kind of outlining why it did it. To add on, the fact Mami didn't know the structure puts her in a better light. Although this does bring a small chance of her coming back maybe if they can recover her Soul Gem? Of course, Kyuubey is ignoring what these girls actually want. For Sayaka her insecurities are so heightened and then Hitomi mentions her feelings for Kyosuke. Of course, she is being mature in realizing Sayaka spends so much time with Kyosuke that she wants her to face her feelings first. Much like Madoka's mom, Hitomi just isn't aware what Sayaka is going through even though her advice is very sound IMO. Sadly, by the end of the episode things look to be worse for Sayaka and, at this point, is doing what Kyuubey wants with her. Simply throwing away her body around.
One aspect of Madoka and Homura's conversation that has me intrigued is when Homura mentions that she is no longer human. Unless it is something I missed, there is a purple diamond on her finger. I wonder what that could be about?
