About Fiona[]
Fiona is a scientist who ruined credibility trying to prove the Loch Ness Monster exists.
She was formerly a research assistant to Sir Ian Locksley until he fired her for trying to find the Loch Ness Monster.
She created two fake versions of Nessie: a land-going one (a mechanical vehicle and a giant model run by Angus and Colin Haggart), and a water-going one (a disguised submarine run by herself, and docked to the bottom of her boat when it was not in use). The purpose was to make Sir Ian Locksley a Nessie believer so he would take her real pictures seriously.
Her plan worked, even though she was caught. Some equipment left very deep in the lake detected Nessie. Sir Ian was convinced enough to join her in the Nessie search. She was not punished for the damage her monsters did.
