Aaron is a sixteen-year-old graduating senior from Bronxdale Prep in You Know You Love Me. He has his licence and skipped 10th grade. In the books he is described as having "a head full of short brown dreadlocks to a boy Blair's age with big brown eyes, pale skin and red lips that curved up in the corners." It is revealed that he has a crush on Blair, but he couldn't tell her because they are step-siblings. Later he gives up after seeing her with Nate, and he dates Serena for two weeks.
In the the TV series Gossip Girl Aaron is an artist who works at Rufus's gallery and meets Serena. There's an obvious attraction between them and Serena later realizes that she and Aaron went to the same summer camp. They begin dating although she doesn't like that Aaron also sees other girls.
When Serena and Aaron begin dating exclusively, he escorts her to the Snowflake Ball while Dan goes with Aaron's ex-girlfriend Lexi. Dan and Serena are both obviously jealous of each other's dates and there's tension between Aaron and Dan.
Dan later asks Serena to not go to Buenes Aires with Aaron and although Serena doesn't get to the message in time, she comes back without Aaron since she still has feelings for Dan.
