The Six Million Dollar Man1974

Oscar Goldman:
[helping the rubber-suited diver in through the entry-hatch, and assuming that it's Steve, but then staring in slightly wary surprise when the diver takes off its mask and reveals the head of a woman] Who are YOU?

Col. Steve Austin:
[emerging from the hatchway behind Violette, and smiling at Oscar in an amused mischievous "surprised you!" manner] Oh, a little mermaid I picked up along the way... she swims for Interpol.

Oscar Goldman:
[recovering from his surprise and remembering his manners, so he removes his coat to wrap around the shivering girl] Well... welcome!
