I'd love to have more CR with Chrom and Jaune, since I adored their first meeting. It's sweet that Jaune looks up to Chrom as a cool guy. He'd be the supportive big brother type easily, and absolutely wouldn't mind having Jaune along for his travels to Santa Village and Nabila.

Keiko was also there for the Another Story event, so if you want to establish any previous CR, I'd be happy to plot something! She's having troubles with the Jobs too, but she did just sort out a bunch of magic skills, so maybe they can mess around with that together.
