--[x] Making dinner with her versus having dinner here with everyone... You love both prospects. Perhaps here today, at home tomorrow?
I feel like suggesting one choice over another kind of takes away from it being her decision. She'll just go with our suggestion.
[x] Mirror Mami's expression. What does she want to do?
-[x] Poke her and glare playfully at her if she responds by asking what you want to do.
[x] If Mami chooses to leave, try to convince Homura that she doesn't have to. Wouldn't she rather stay? It's easier to protect Madoka from
inside the house, after all.
-[x] Before leaving, make Homura a Clear Seed. Step outside for a moment for privacy, if need be.
-[x] Go home and have dinner with Mami whilst being extremely affectionate.
-[x] If Mami has no other plans for the night (homework?), suggest trying to work on some enchantments.
[x] If Mami chooses to stay, spend dinner being casually affectionate with her insofar as you can while observing dinner table decorum.
-[x] Tell Madoka's parents things that reinforce what a good person their daughter is, and how glad you all are to have her as a friend.
-[x] Take available opportunities to say things that will remind Mami that she has quite a few good friends now.
-[x] Where possible, try to subtly encourage the MadoHomu agenda.
