Bentley: I hope you realise that by saving Carmelita we're only making our operation more difficult.
Bentley has found out that Don Octavio has hired the Blue Viper Gondola Gang to dispose of Carmelita, who is on her daily patrol. Bentley hot wires a police gondola and takes the turret, while Sly drives.
The canal Bentley and Sly are chasing the Vipers in is packed with other boats, so they'll need to jump when necessary. After defeating the three Vipers, Carmelita is safe.
