In the Series Edit
Jessica was met in London, alongside Charlie, Leonardo, Charlotte, and Ronnie. She moved onto Poseidon, where she then travelled to North America, taking a helicopter with the English Resistance Commander, Alice, to Colorado. After meeting the leader or the North American Resistance, Aki, she was ordered to join Faith's group who were destined for Europe.
After rendezvousing with the group in South Carolina, Jessica joined them on an aircraft carrier, destined for France.
Jessica is a level-headed girl who tries her best to fight the Arume in any way possible. Despite her calm attitude, she's often uncomfortable around strangers and usually finds it hard to talk to new people. However, she tends to fare better when it's someone else who starts the conversation.
