After Teyla Emmagan is seriously injured in an explosion, Marie aids Doctor Carson Beckett in the surgery and expresses surprise at Beckett being able to stop a major bleeding. After Beckett is warned that Doctor James Watson is infected with an explosive tumor, he orders his medical staff out while he closes down the OR level. However, Marie refuses to go, telling Beckett he can't do it by himself. While Beckett is initially frustrated by this, he thanks Marie for staying. Together, the two remove the tumor from Watson, saving his life. Beckett then leaves Marie to close Watson up while he takes the tumor to an ordinance disposal technician. However, moments later, the tumor explodes, killing Beckett and the tech. (SGA: "Sunday")
