During the next judging round, host Tyra Banks was still not pleased with Jean's haircut, wanting to make it even shorter and scheduling a time to have it redone but Jean refused.^[10] Claiming that the producers gave her one night to consider her options, she walked out the following morning.^[11] During her time on Top Model, Jean took two photos and received one third call-out and one first call-out. Jean's choice to quit and Sarah Rhoades' elimination during the same week had later forced a non-elimination episode where together both Jayla Rubinelli and Nicole Linkletter (who eventually won over Nik Pace) survived their first-ever bottom two appearances each. Jean made an appearance in The Cycle 5 Reunion, America's Next Top Model: Where the Girls Are, and America's Next Top Model: Exposed.^[12] In 2009, she was voted one of the most memorable contestants by AOL Canada entertainment.^[13]
