With a speech check, Belle will tell you where Pinkerton can be found (in the broken bow of the ship).

Appearances
 only appears in Fallout 3. Her name may be an ironic reference to her appearance and general demeanour, as 'Belle' and 'Bonny' mean 'beautiful' in French and Scottish respectively, while she is an old woman who speaks very rudely to the PC.
