We have to get an MRI on the ship before it leaves the port and do the scanning and removal en route. They can dump the trackers in the water before reaching the North Sea and disappear."
Since they have to wait for the ship to get there anyway, why not just compel a doctor to open a clinic and start scanning overnight, starting with the humans that leave the compound regularly, then the most human looking ones and so on and so forth. I swear this shit be not strategic or well thought out. The author already said how many hours it would take the ship to be ready to leave and to get to their port, plus Turner is looking for overnight lodging so it just makes sense.🙄🙄
