Chapter Nine: The Piggyback - S4-E9
Corrected entry: Stranger Things season 4 vol 1 confirms upside down is locked in 1983 as Nancy's guns aren't there. Her diary entry shows it to be Nov 1983. Yet in season 4 vol 2 Ed Munson's guitar is there. This implies he either was playing guitar back then or they've made a deliberate mistake here but it's caused an error in the 'stuck in 1983' story.
Correction: This entry needs clarification. You acknowledge the possibility that Eddie was playing guitar back then, so how could it be impossible for his guitar to have been there if that's the case?
