Thing is? If that's the case, about all we can do about is... go there and try to save Sayaka. This all ends with going there, saving Sayaka, and tearing the witch a structurally superfluous new behind. There really ain't much we can do to prep for that. We'd still end up fighting it, and we can make any grief preparations we need when we get there if necessary.My point is that there are narrative reasons to suspect that the witch fight will not be easy. And there are a number of different effects that would prevent Homura's time-stop from working.
