I have a memory of a show I used to watch obsessively as a kid, I might have had it on tape. I've been trying to identify it for years. It might have been Johnny Quest or something similar/ripoff.
All I remember is the group is in some underwater lab, and it starts caving in. The robot member of the group makes it to the surface, swims to shore(?), and is stumbling around calling out for "Joan". It's going, "Joan... Juh-own.... Juh-own...."
