"Conaaan!"

She approaches, hands in her pockets. Then suddenly she swoops in for a tight hug, lifting him off the group with a laugh.

"What're you doing off the train on your own?! Do I need to get Raaaan~?"

Yes, she did hear that broadcast, and yes, Dair's gonna use this as an opportunity to tease him.
