If the author wants us to feel the tension of her working without Atra or Silas for the first time maybe don't preface the situation with someone saying how the location is next door and they will rotate three groups, so they will be gone for like what, a day or two? Also we have no reason to believe that other knights will come by to bother her or be douches since so far everyone seems to like her, so what drama is the manga trying to make us apprehensive for?
