This has happened before. Saying it is unfortunate is an understatement. According to reports the passenger refused to stop eating the peanuts. Before you make any comments like "wow he was 10 rows infront of her, she's not safe anywhere" and other ignorant remarks - take the time to understand the basics of food allergies. You are in a plane with other passengers on recycled air flow and airborne allergies exist. Its not difficult to understand.

Compassion is free.
