The laboratory staff were acting strangely, not sure what kind of research they were conducting. Lu Xiaodao said they haven't had a break these days, seemingly having their own tasks, unlike being here to pick people up.
Maybe Captain Jack's support team and the laboratory are just two independent departments working in the same office building.
Moreover, Lu Xiaodao saw cages for animals in the laboratory, of various sizes. What he saw were all empty, but there were bloodstains inside the cages.
There are no mice to be found at sea, so they must have started or prepared to conduct experiments before setting out.
So, their experiments shouldn't have anything to do with us. I heard that some illegal experiments are conducted on the high seas, disguised as fishing boats, avoiding much scrutiny.
If what's stored in the laboratory's refrigeration unit is some kind of dangerous virus, once spread, the team leader and others would also suffer.
