Linius Ginehart became busy for a while after Lieutenant Arc Lisbon called for him. He wasn't able to immediately return and continue with that conversation with the master. It took him at least three hours to finish all the paperwork that the lieutenant kindly dumped in front of him.
He thought that those documents were destroyed during the attack but to his amazement, Lisbon actually saved them and put them to safety.
"Those documents are important and it would be a headache if they got burned because we won't be able to produce those again with all of the revisions done on it," he reasoned. He was too serious when he was saying those words that the major couldn't refute his words nor his actions of prioritizing those pieces of papers.
