Traveling with her is Vera Campbell, her governess, who is unnerved and faints during boarding, having survived the Titanic's sinking four years earlier, losing her husband.

She discloses to Captain Barrett and First Officer Townsend that she is an operative of British Intelligence, and suspects a German spy has boarded the Britannic.

Although she reports odd sightings and behaviours to the captain, Barrett scoffs at Vera's notion, and refuses to take her seriously, though Townsend grows more warm toward her.
