As evidence of her wartime Nazi collaboration, an Iron Cross awarded to Kerttu is presented, stating the inscription has her name and reason "services to the Reich" are there. Iron Cross was very seldom awarded to civilians and the recipient's name, let alone anything else, wasn't inscribed to the backside of the medal. They were in the awarding letter, however, this is not presented.
As Rebecka and Hjalmar both have fallen in a hole in the ice, chasing police cars drive very close to the scene and policemen exit their vehicles to come to the rescue. The ice doesn't break under their cars or policemen, while it has already broken under Rebecka and Hjalmar's snow scooter.
Rebecka runs on the ice with Hjalmar chasing her in a Polaris snow scooter. The ice breaks first under the snow scooter and only after that under Rebecka. Considering Hjalmar is following Rebecka's tracks, ice would more likely break under a running person than a speeding snow scooter.
