I don't need your pity. I'm still a bitch.
— Cassandra Kopelson in Pilot

Cassandra Kopelson is the gorgeous and popular first-year surgical intern and who just happens to be Emily’s high school nemesis.

She had a sick brother in high school, which made her life difficult. It is known she used to be jealous of Emily's smarts, which is why she bullied her in high school.

Early lifeEdit

Not much is known about Cassandra's early life, other than the fact that she bullied many in her school days. We do know that her brother had a disability, and in S1E01 she explains that she could never have friends over because of it. However, later in the season she references how she had more of a social life than Emily ever did. We also know that Cassandra beat Emily in a spelling bee in elementary school.
