I'm reading Finding Me by Michelle Knight, the first of the three girls kidnapped in Cleveland and held for over ten years.
There is a chapter about her having an anaphylactic reaction while in captivity.
[spoiler]she said for many years he brought her food without her allergen! and he was aware of her allergy. Then one day....it was eat this or eat nothing[/spoiler]
It was quite bizarre to come across that so unexpectedly.
Holy cow. Very interesting.
*Shudder * As if that case wasn't creepy enough.
