"It seems that working overtime on Christmas is meaningful, such as when historical sites appear regardless of whether it is a holiday or not." More than an hour after the phone call, Doctor John from the National Museum came with a few people in a car.
Leonard Ethan had seen this Doctor John several times, such as when he first donated the Irish national flag, the doctor accepted the gift on behalf of the museum, and he had seen him on the way before discussing issues with the director.
If Leonard didn't remember wrongly, this doctor was in charge of donations and handling of field historical finds for the National Museum, so theoretically, it wouldn't warrant his involvement for such a small historic site.
"It's a bit lonely to be alone at home on Christmas, so I'd rather be on duty and be happier with everyone else." After Leonard greeted him, Doctor John voluntarily explained.
