I'd love that! Arid can maybe wake Luna from her trance before the poor girl goes traipsing out into the snow barefoot not out of the goodness of her non-existent heart, mind you, but more bc bafflement loves company

Arid is also going to be spending time with Paimon at the party, too. Maybe Luna can spot the two of them hanging out and thus have a vague idea that they're connected when Arid wakes her from her trance?
