The flight attendant was a lady serving Team Ragnarok during their plane trip.
Team Ragnarok were curious about the phenomenon caused by the falsification of history. She noticed that they were acting strange and asked if everything was okay. Brodor asked if she noticed the plane shake, but she didn't and asked what he meant. Halldor insisted that it was nothing and thanked her. She then left, leaving the team to discuss that they are the only ones who noticed the phenomenon.
