Now I don't know whether we should consider this a clue, but did anyone else notice the boxes in the storage-room where Bertram goes in 6.07? 

In two different scenes you can see boxes saying "Shand Creek" and "Seven Graces", Valley winery/cafe, both addressed in Napa Valley. 

And if you recall, both of these places were featured in episodes that had Sheriff McAllister in them. And not to mention the wine bottles in the room and Bertram's id named to a "Thomas". 

What are your thoughts about this?
