The old man who had been silent the whole time said, "I'm Professor Eric Selvig. I mainly study astronomy and physics, and I'm also an astronomy fan. How can you tell?"
Luke turned his head and looked at the jeep on the side of the road. "I don't know many things, but that telescope isn't cheap."
Professor Selvig said, "As expected of an officer. You're very observant."
Looking at Professor Selvig, who had a bit of a scientific air about him, Luke asked decisively, "How should I address you?"
"Jane Foster," said the older woman.
"Darcy Lewis," said the younger woman.
"Thor," said the tall blond man with a beard.
Luke simply looked at them and didn't act out of the ordinary. He just nodded and said, "Nice to meet you. There haven't been any meteorites here recently."
