The cold opening of the episode featured a flashback to a scene in the kitchen of a house in Spain. However, not only are the appliances, countertops and cabinetry entirely out of character for a Spanish or even a generic European residence, but the power outlets visible in the kitchen are clearly of the 110-volt type used only in North America rather than European-standard 220-volt outlets, revealing that the house is in fact most likely located in the United States.
The new house in "West Texas" doesn't look like *anything* in West Texas. Maybe Colorado, maybe Montana or Wyoming, but there is *nothing* in West Texas like that house. (And the terrain is definitely not West Texas.)
