For me the dream date is a treasured memory that could help fill the white materia, I don't buy into any negativity, like Cloud doesn't know the church (he was teasing her), the church is also a place of quiet and peace for Cloud, important place for them, as noted in the Ultimanias, and where he goes in AC. Again I think if the intention was to make people not enjoy the date, they fumbled very badly.
(I'm not saying the church isn't an important ZA space, I just think it's a sacred space for everyone)
Edit; Well I want multiple endings because I don't want to be to feel like a joke or made fun of for years, I want everyone to get some happy, and some content for people to use in their fan videos, etc. On the contrary there are extremists on both sides that convinced that they are right and will win and their way is the only way so they refuse to entertain any other option, they are convinced one girl or the other will lose, and are ready to revel.
