Selphie not only bears a rather strong resemblance to one of his sisters, but they also happen to have similar backgrounds, both being orphans enrolled in military schools governed by Evil Looking Moms™! He's not much of a responsible adult, but he could still be of some use if you'd ever be in need of a police officer and his boring, motivational speeches. Idk, I'd just be interested to see where these two would end up, so I'm fine with anything!
