Shivernight Manor

Eventually, Ophelia will cry, but more from frustration and rage than the onions. She spends much of the early torture screaming obscenities at Bluefoot and at Sapphira (though she's not there). But partway through, there's a surprising change. She becomes stoically silent, not responding to anything done to her. She seems be focused on something no one can see, occasionally muttering curses at it.
Of all the tortures, depriving her of food and eating in front of her seems the most effective. Judging by her appearance, she was probably somewhat malnourished even before she was captured.
