As the marine biology student worked on fixing, welding, his personal submarine - the SoloSub1- he was videocalling his girlfriend.
Though they both lived in very different climates - he was out in the ocean city colony, while she was in the desert colony - they were well connected.
Both of them were students of science, aware science had dramatically improved their lives, as well as the lives of those around them.
He saw it every day under the sea in Sea Castle. She saw it every day out in the Mesa Verde desert. And they saw it every say when they videocalled.
A/N:
I love that scene in the Horizons ride where the animatronic girl, the narrators' granddaughter, is talking to her live boyfriend on a videocall and then in the next scene, she is live on the videocall and he is an animatronic. That's really cool. Disney needs to do more scenes like that.
