Curious

He was probably still alive at that time unless she convinced herself that it happened when it never did

Or maybe he was already dead.
Remember the coworker/part time guy? The one with short hair, he always looked at Emma with disgust or at least he thought she was strange, wouldn't it be plausible to say that he was already dead and she was talking to herself all along?

Oooooh maybe

i think he was already dead dat time cuz the other staff is saying dat shes weird..lol
