None of us reacted appropriately to when you arrived. Least of all me. This isn't the same situation at all in regards to Regina, but even if you're not up for helping Allana with her idea, if you could write down what you think would have helped it could make it easier when something similar does happen. Open communication would definitely be the first on that list.
Just because a version of you does something to Kon doesn't mean you have to follow down that same path either. This is a different world from what either of you knew, the same mistakes do not have to come to pass, but I'm sounding preachy and I don't want to sound like that.
I don't think the other safe places are the best bet for Regina simply because there are still others there that she could harm.
