They walk deeper inside prison block and pass another heavy armored door. Commander use his pass and it's opened showing picture of further space. Many cells with heavy metal doors and little windows for guards to check if something going on inside. Inside air was stale and damp. Not best place to stay for long time.
When they reach door, looks same as all others, commander used not only pass but also keys. Looks like it was made as additional security opportunity. "Go inside. Soon you will be investigated." commander replied to Rai. Inside cell was, bed, table, chair, toilet and sink. Light was little faded but it's happened time to time. Nothing actually to do except sit and sleep.
