The visit to the training ground was only brief, as Ophelia only wanted to get a glimpse of what's happening in their training as well as evaluate the condition of the recommended knights that will be joining in the annual inspection.
It was not one of the top priorities for Ophelia to go to the training ground and evaluate the knights. She can give that job to the Knight Commander, Bernard, to make sure that all of the recommended knights are ready for the annual inspection.
However, Ophelia was curious about the training ground when it was mentioned, knowing she didn't find any memories about it through the original Ophelia. She made use of the opportunity and did the job itself.
Since she was not originally responsible for this job, the time allocated for it was only limited and brief, resulting in her not satisfying her curiosity and fully exploring the task.
All she could do was pass the task to the knight commander to finish the job.
