falling up stairs
“Terissa falls up the stairs, Terrisa falls down the stairs.” This was said during one of Locke’s dreams in season one. A bloody Boone repeats it as he watches the nigerian plane crash. Turns out Terissa was Boone’s babysitter that he pushed down the stairs, breaking her neck. Terissa is also the name of the girl that Faraday merked with his experiments. (Desmond sees her in season five). Same person maybe?
