Returning to Hospitality, Melanie broadcasts a message officially handing control of the train to Layton. Consumed with guilt over leaving her daughter behind to die, Melanie visits Miss Audrey to get some solace.

After a confrontation with Ruth, Melanie returns to work as an Engineer investigating a strange signal that proves to come from ''[[Big Alice]]'', a Wilford supply train with a prototype of the Eternal Engine. As ''Big Alice'' clamps onto ''Snowpiercer'' and begins taking control, Melanie, worried that the other train contains the real Mr. Wilford, chooses to climb outside and cut the uplink. After angrily realizing that Bennett covered up the approach of ''Big Alice'', Melanie heads outside alone, cutting Bennett's air supply so that he can't follow her. However, ''Big Alice'' brings ''Snowpiercer'' to a stop in the middle of Chicago, throwing Melanie from the train. Surviving the fall, Melanie begins making way along the stopped trains, unaware that her daughter had just boarded [[Snowpiercer]] from [[Big Alice]] as Wilford's diplomatic envoy.<ref name="Long" />
