In Ruins of Phandalin the party meets the stable hand Tim. A simpelton, by any measure, but he seems to be goot to the horses. 

After a series of events, the party ventures back to Rivergrounds, where they go to the stable to buy horses. 
Margerie is the stable owner, and as Willowbark talks to some horses the stableboy emerges. Kal recognizes him as Tim: He is the spitting image of the other Tim, has the same name and is as simple as the other Tim. He has no twin, and both seems confused when Kal enquires about the situation.
Tim in Rivergrounds packed his things and ran away after being confronted by the party

The part is suspicious and intrigued to find out what the deal is with Tim

When arriving at Chasten Crossing, Elmroot spots a "missing persons"-poster from Tim and a picture of Tim.
It directs them to a person named Vikki. 
Vikki tells them he ran away from home and his parents have been looking for him, and one day they were found dead in a river. 
Has been missing for 6 months at this time, son of farmers. Described as very nice and highly intelligenty. 
He mentioned some friends settling down close buy before he dissapeared
