Whose cell was Corrie allowed to see in as she walked back to her cell from her hearing?

After the hearing, Rahms tells Corrie to walk slowly in a certain corridor where she sees the back of Betsie’s head. Corrie also sees that Betsie has made her cell beautiful, almost a home. This comforts Corrie somehow to know that Betsie is making Scheveningen a little brighter.
