great! nia would probably step up and be the bolder one when they were kids if he's a bit on the quieter side. she could definitely relate to the culture shock since she and her parents were living in small town louisiana before they moved so they could bond over that too. she'd be supportive of it all though even if she's like wtf. they could have kept in touch while he was in europe, maybe she visited him a few times? and she'd love the whole rainbow of stories and play along if he ever needed the backup
