I was going to offer up Fred with Hayden, but now it feels as though Hayden will be too busy.
Ms. Pearl and Cascada could have something since they're both djinn. She could find amusement in Cascada's novice ways compared to what the older djinn has seen.
It could be possible to have a James/Fred interaction where he sees that something is going on in her mind. I doubt he would do anything to help, but he could find amusement in it.
I'll offer up everyone except Kat really if you have anyone you're interested in. Katherine's already having a big night.
