TinyMeatball didn't obtain useful information, but he figured out the strange incidents were caused by a massive migration of Eternal Kingdom inhabitants.
As long as the investigation continued on Eternal Kingdom's Gnomes and Houndhead Men who came to Winterfell to work, there would be results.
After he questioned TakeASpearHit and the construction site supervisor and confirmed that TakeASpearHit was a diligent worker, he went to other construction sites to investigate.
The investigation process was hard. The Gnomes and Houndhead Men seemed to know some information, but when TinyMeatball asked an important question, they would decline to answer or say that they didn't know. Very few of them had the reaction of TakeASpearHit, who said, "Gosh! Is that a crime?"
Or similar shocked expressions.
After half a day of tedious investigation, TinyMeatball returned back to the station with Peanut. On the way, they discussed the details of the cases.
