Pippa is all about cute boys with Spanish accents and will probably go all giggly and pink around Rafael if he notices her. She's not a rule breaker (unless under the influence of more wayward/rebellious friends) and would be mortified if Rafael ever had to take points from her.

Henrietta, on the other hand, is a naughty child. HI RAF. She doesn't break rules for the sake of it, she just... does her own thing, and sometimes that happens to be in direct conflict with Official Policy. (But if you're not hurting anyone, what's the big deal?) I think she'd enjoy playing Rafael's detective vs criminals game since she's also super competitive, haha.
