The prompt was from a--deity, Varian jealous over Cassandra, but fluff. It was quite difficult to do in 100 words ;-)
****
Varian couldn't concentrate for jealousy, he'd seen Cassandra talking with another man, why did it have to be another scientist?
There was a knock on the door, he looked up to see Cassandra stood there. Strangely, holding a rock out to him. He took it, it was glinting and heavy.
"It's a meteorite?"
"I thought you might want to figure out what compounds it was made of."
"How?"
"I don't always understand what you do. So, I didn't know how to get you a birthday present that you would like. That's why I was talking to Durnik, he suggested it."
