In a lamp-lit scene where the Dickinson family sits in the drawing room, Emily is reading a book. The lamp is on the opposite of the print. There is no way she could have seen a single word on the page.
Emily says she writes at 3a.m. until 5 a.m., yet she is sometimes seen writing at her desk in what appears to be broad daylight. Though she writes a lot, no ink stains her fingers or her sleeves.
Emily's brother refers to the draft and the fee for avoiding it right after Fort Sumter, in 1861. The draft and the fee were not established until 1863, and in 1861 everyone was sure that volunteers would end the war very quickly.
The Bahn Frei polka played in the dance scene had not been written at the time.
