So I do not think she and Sandy have ever met. Ever. Sandy's family might be known prior to Calypso's departure but this little half Irish-American half Outsider kid is new. But she's friendly?

And I suspect Chris has never had the chance to meet Cal. Makes sense, old family with little connection to a school teacher (even a smart and fairly hard to intimidate one). HOWEVER he absolutely understand the depression thing. Though he wouldn't call himself depressed.

Also, I love Cal for she's a blonde Spade. ♠♠
