irnan's theory totally makes sense here -- especially because I've vaguely thought of Force-ghosting the way I saw it on TV Tropes once (lol): choosing to tie themselves to the mortal world forever to help those living there rather than to transcend or whatever. Which makes perfect sense for Skywalkers, but I think Arissa's a bit more about Arissa. In a nice psychologically healthy way.

I also love the idea of Anakin being skeeved out by it -- because for all the people whining about how he must have used his mastery of the mind-trick on Padmé ... what mastery? He never uses it ever. Not even as Vader. So I can easily see him being horrified. Even the transmitter didn't completely strip them of agency.
