Alright, so I also have three characters in the works. Here they are, and whom they would be good with.
Jaime Schanbacher: An archer, a swimmer, and a stubborn, rebellious snark knight. Currently in the Final Apps queue.
Sabrina Luz: Younger sister to Emma. A ballet dancer and chef. Originally had no disadvantages on paper, but that is to be changed. Beautiful, intelligent, good-natured. Also, and this is important, a closeted lesbian. So one woman might know, and it would be a relationship.
Manuel Figueroa: Created when NAFT had his challenge. Smart, and can't wait to tell you how smart he is. A baseballer, a footballer, and a budding director.
Danny would be likely to know both Sabrina and Manuel, being a ballet dancer and a footballer himself. It wouldn't be surprising if he'd asked Sabrina out at some point, though whether she would have accepted or not is up to you (I'm aware of the lesbian thing but obviously Danny isn't) and in either case it wouldn't have gone far due to Danny's tendency to be flighty.
Also Lily is one of Sabrina's cousins, being a Luz, so there's probably potential for some sort of connection there.
