I'm trying to quote 1984 for a research paper. This is the original quote, line breaks preserved
‘We are the dead,’ he said.
‘We are the dead,’ echoed Julia dutifully.
‘You are the dead,’ said an iron voice behind them.
They sprang apart. Winston’s entrails seemed to have turned into ice. He could see the white all round the irises of Julia’s eyes. Her face had turned a milky yellow. A smear of rouge that was still on each cheekbone stood out sharply, almost as though unconnected with the skin beneath.
‘You are the dead,’ repeated the iron voice.
‘It was behind the picture,’ breathed Julia.
‘It was behind the picture,’ said the voice.
First, do I keep the line breaks for dialogue? Second, is there an appropriate use of ellipses within a block quote? I get that it's supposed to be a long quotation, but the parts of the quote not expressing surprise are effectively irrelevant to my thesis. Purdue OWL only mentioned block quote ellipses in the context of poetry
