Well, If you can find a second Usdia for it, I can offer
Cephy o'Pod. She's rather a water baby, but she Isn't exactly the best swimmer ever and used to slower water. Knows how to get out of a rip current but if she ever left the beach and went upstream to explore a little, and a flood happened, it'd be easy enough for her to be in trouble in a river.
As for the latin, hopefully I'll be getting Cuauhcoatl soon (if not by the end of the month, soon afterward by a different colorist). He's been around a long time before finally taking the form of a Soquili as an Angeni of learning. He likes teaching people things, since you learn best while teaching. So by speaking latin to teach her and studying it a bit more to get better, it'd strengthen him as well.
