The Raccoon - S1-E10
Plot hole: The plot gets confusing here. First, Laura and Jack (the dog) are rabidly bitten by Jasper (her pet racoon). The doctor warns they may have rabies from the bite. A second more dangerous raccoon is discovered which eventually left the area. In the end, Charles (discovering there were two raccoons in the barn after finding Jasper remaining), says Laura is going to be OK after all. The main confusion is that Laura would still be in danger from the bite regardless of which untested raccoon bit her.
