Florence Tipton is a young American woman who first appears during the show's fourth season, and is a recurring character who appears in around twelve episodes. She is a sciencist, like Scorpion, whose lab is next door to Scorpion's garage.
In "Go With the Flo(rence)," the Scorpion is in the garage when a rotten eggs-like smell comes through the vents, which turns out to be a revenge plan by Florence against the Scorpion, who are making too much noise.
