(Verbena is one of my Cilan/Clemont kids!)
She’s technology oriented like Clemont is, but rather than inventions and robots, she enjoys coding and programming, especially thinks like code-cracking, writing robot AI, and hacking. If there’s a puzzle to solve that involves code, Verbena is going to want to take it apart and tackle it.
That said, she also has a habit of messing with tech she shouldn’t and has gotten in trouble with school before for messing with teacher’s displays and the like. Whenever they get a call from school about her, Clemont is sure to give Cilan his best stink-eye since Cilan was the one who sparked her interest in coding in the first place (it being something he’s good at.)
Verbena is a pokémon trainer, but she’s not got any real ambitions beyond learning new things and spending time with her computers, so her parents sort of pressure her into trying to challenge the Kalos League to give her something to do (and she actually ends up really liking it, enjoying these high-stakes battles more than just fun battles with her fathers or brothers.) I’m not sure yet who she travels with though.
