Margo was a good friend of Thea Queen's and fellow student. It is presumed that Thea broke off all of her friendships with those had a bad influence on her.


Margo had crushed up some pills for her and Thea, before Oliver walked in and she was forced to swiftly hide it, leaving to allow the two to talk, and telling Thea that she'd see her at school. She was later at Oliver's homecoming party, but left along with Thea and the rest of their friends, though not before asking Thea did she have the drugs, but after not being able to find the packet it was contained in, Thea told her she must have dropped it.[1]

Margo and Thea later planned to go to the mall, but Thea was grounded by her mother for acting out.[2]
