Hoscut Witterel was on the main deck during the Kraken attack, looking for her husband, who was below deck trying to force the mermaids to call off their Kraken. The Kraken broke a piece of a sail, which crushed her, as Paul Moss, Emily Jackson, and Jane Bird watched in horror.
After she died, her body was taken to one of the port side cabins on where it remained.
Hoscut Witterel can be identified in The End, part 4 when Captain Witterel addresses her by first name and mentions his love for her. At this time, she can also be found tucked into bed in the cabin directly attached to the Captain's cabin, which indicates that the captain cared deeply about her.
In The Doom, part 8 she mentions that she is looking for her husband, the captain. With this information about their relationship, it is deducible that the two share the same last name. Shortly afterwards, she is struck and killed by broken rigging during the attack.
