Could also be used for a reconnecting event between Luna and Cordia.
Or a family trip of all three/four of the girls. Could be quiet amusing if even some serpents where there and all the possible interaction from them with the townspeople. Hopefully none of them will be permanently damaged.
With Luna, perhaps it's just me but I think I would prefer her to be at Cordia's bakery after her and Cordia hash things out & had fully reconciled (with the help of MC) somewhere else.
My reasoning for that is as Hopes explained above, Cordia loves cooking food, and it is something she does in her downtime to relax and perhaps be at peace. Not sure it would be suitable place for those two (Luna & Cordia) to try to reconcile there (since their relationship now is on shaky footing), plus the shop would be getting customers.
So where do I think are suitable places for their reconciliation event?
I'm thinking places where it's quiet and tranquil, like Musala Hill (Luna's Bee event) or fountain in 0.065 (where MC & Isabel patched things up completely back to normal), with beautiful sceneries.
These two (especially Luna) would have pent up feelings about what happened, so I think they need a private place to hash out their emotions (such as yelling in anger, crying or something else) at each other with MC present as mediator possibly.
And after the two of them completely patch things up, perhaps Luna can join MC to work a day in Cordia's bakery.
A family trip, I can see that happening, but perhaps later down the line, after we get at least couple of solo-Cordia events first (like with Isabel, we had couple of solo events with her, until we had the shopping mall event [with "I want a diamond gun, diamond car" where Luna & Gracie came along with Isabel]).
Come to think of it, while a trip sounds great, I think it would also be pretty cool if the entire Family (not just the girls, but everyone, which includes Wilfred, Antonio etc) was invited to a formal event where the family members get to mingle with other mafia families (like rest of the Big 5, plus the smaller families).
It could be a nice way to introduce Cynthia (who Gracie says, usually accompanies Cordia to formal events).
But regardess of my theories/conjectures, I'm sure Hopes has something in mind that's fun & exciting.
