Corrected entry: Johnny predicts a fire at the restaurant and his warnings and those of the sheriff go unheeded. However, everyone seems to just shrug and walk off and leave the restaurant to its fate. Given the response of the sheriff to Johnny's predictions in the past, even if the owner of the restaurant wouldn't close down they still could have had officers at the restaurant. The prediction said the "doors would jam" and so an officer there could help break them down. Or even better, maybe have the fire department on standby.
Corrected entry: Johnny tells Madeline that he was in a coma seven years ago. However in previous (recent) episodes that he has spoken of the crash, he said the accident was eight years ago.
Correction: There's nothing factually wrong here. Johnny didn't say he fell into a coma seven years ago, he said he was in a coma, which makes sense - the crash occured before the coma.
Corrected entry: When Johnny comes to see Walt, Walt doesn't recognize him until he tells him who he is. But, we see in future episodes that Walt already saw Johnny with Sarah at the hospital while he was in a coma.
Correction: While he may have seen Johnny before, he didn't know him. He wouldn't necessarily have made the connect that the guy in front of him was Johnny, especially since Johnny was lying in bed in a coma the last time he saw him.
Correction: There would be no way for the sheriff to legally keep officers at the restaurant. No crime has been commited. And while the sheriff might believe Johnny, the danger isn't one he can rationally justify to the restaurant owners.
