Nadia, Nicolas and Zoe Cray

These triplets are so adorable.
Nadia is a doctor.
Nicolas is also a doctor and the cutest trans boy 
Zoe is a maid and her parents are forcing her to be a doctor like the rest of her family. Nadia calls Zoe 'Zoz' all the time
Nadia and Nicolas are both in the death club and are good friends with the other members. (They poison people who survive the Death Club's antics). Zoe is Sara Kelly's best friend along with May. Nadia and Nicolas are concerned about Sebastian's (Rin) well being since they overwork themselves writing people's personal information to sell and finding this information. Normally they have to calm Rin down or put sedatives in their food or drink since Rin endangers herself (I change Rin's pronouns every 10 minutes and I use all pronouns for Rin) by not sleeping or eating most of the time and they (Nadia and Nicolas) get way too concerned for Rin's safety.

The Cray Family are a family of doctors who revolutionized medicine throughout history. 
Their parents are always working and they are both brain surgeons (The Cray Family marry doctors and nurses)
Their aunt (who is a transgender woman, her birth name was Henry) is a gender therapist, a surgeon and is quite supportive of Nicolas (his birth name was Gabriela)
