I think Jack would be kind of Mechanic because he fixes things like old trucks,broken cars and stuff like that.Dr.Shumway does not believe in aliens so she would be sciency and all like that.Grady would to be like a bully because he hates Jack.I think Sargent Web would be demanding because he is rude to the others.Isadora would be scientific because she is into the aliens.Uncle Bud likes to make inventions so i would call him smart.
