Gregg transferred from Woodford to replace Skippy. Gregg had a brilliant singing voice and entered the talent competition at the Ship Aground, singing a version of Bette Midler's classic 'The Wind Beneath My Wings'.
Gregg went out with Tiggy, who was an art student who he met when the Watch were called to a flooded Art Exhibition. Gregg went out with Tiggy a couple of times and the press photographed them. Gregg didn't have a clue why it was happened, until he read the paper the next morning - Tiggy's father was an MP.
Gregg burned down Upham Fire Station, while the pump crew were on standby.
It was a hot day and the fan in the Watch Room was not working. A circuit breaker had been removed in the electrics, so Gregg put it back in. Then, when Upham's crew returned, they found their station ablaze.
