i would be treating them like, after the second movie, alsa yaanand alsa, as adults. i think that a big part of helping them feel connected and have a healthy attachment to each other would also be them kind of experiencing and talking about some of the things that did happen. Also, like it anna's memory was wipedat some point. Soalso, so i was also just kind of like, but elsa remembers all those things happening,. And sometimes i can help clarify for the other sibbling, like, hay, so this is actually what happened.
