1. Blaine Goodfellow rents a house from Associated Properties in Abilene, Texas. He is there for two years, and during that time he installs a ceiling fan, custom-builds a bookcase for an alcove on the main floor, and replaces the screening on the front and back doors, saving the old screening in the furnace room. When his lease expires, he leaves, and the bookcase remains behind. Blaine does, however, take the new screening after replacing it with the old screening, and he removes the ceiling fan and puts back the light. He causes no damage to Associated Properties' house in doing any of this. Discuss who is the rightful owner of the screening, the bookcase, and the ceiling fan after the lease expires.
