We could also bring up the possibility of witchbombing Sayaka to Homura right now,(that is, bring up the possibility right now, not actually suggest to immediately witchbomb sayaka) but whether Homura is up for that talk right now I don't know. On one hand, she might need some time to recover from that talk, on the other hand, talking business might help her cope a bit. Personally leaning towards 'not right now'.
Up to you guys, though. I'm probably not going to be voting much anymore: makes me anxious. So I'll just try and contribute thoughts and suggestions instead.
EDIT: I'll also mention that Tsubaki Mikoto, by canon, would probably have witched out by now. After all, she witched out in the titular character's backstory. However, this is only a 'probably', and even so, Madoka's wish may very well have altered things so that we at least have a chance to save her. 'Everything can be fixed', after all.
