-[x]Ask Homura if she wants to hear information that we believe she might take badly.
-[x] If yes, inform her that Madoka's potential has been increasing due to Homura's efforts to save her.
--[x] note that this information doesn't cause any real changes in the grand of things as long as Madoka doesn't make a wish, after all the Incubators efforts to make her a magical girl doesn't change because Madoka was able to be one before the loops started, and that Wally was going to come here no matter what Madoka's potential was anyway.
[X] Keep talking.
-[X] You know how to keep Madoka from Wishing: First part is beating Walpurgisnacht, but what really keeps her from Wishing is learning what Wishing means... for Homura.
-[X] When Madoka learns about Homura's struggles, pain, the loops, she respects that. That's what keeps her from Wishing.
-[X] Offer Homura whatever support you can.
