the whole scenery in the first quarter was pretty much catering to the audience rather than for a good reason. it was pretty much due to the fake world though so I ended up letting that part go instead of criticizing it.
and the scene with sayaka saying she regretted kyouko could be interpreted as just her knowing the extent kyouko has done as well as spending time with her... while its also pretty easy to tell that kyouko is a lot more affected by sayaka, so I can see it being a one sided matter.
as a side note, this does say quite a bit about homura
she pictured a world where kyousuke and hitomi got together while kyouko was made to end up with sayaka there....
