She has a tattoo that says "Mary had a little lamb" because her mother is called Mary and her nickname was/is "little lamb". Also, cute Nursery Rhyme.
Her younger brother Jason is also an actor. He was in an episode of "Manden med de gyldne ører" in 2009.
His vocation is as photographer, sometimes helping his sister when she directs.
She may be the girl that she/Brandon sings to in "Just Another Girl" — part of the song goes "Now Jason's getting married in the blink of an eye/ I got an invitation but I didn't reply/ Tell your little brother that we put down the glove/ And give him all of my love". Unless the topic is switched mid-phrase from 'Jason' to 'little brother', it is assumed that they're the same person. Jason Agron, her little brother. Now, was the song written with this in mind or were they just lucky that the girl they cast actually had a little brother called Jason?
"I went to see a fortune-teller..." since she's visited psychics before also points to it maybe being from her perspective instead. Which would also mean she likes girls.
