Who is Lula from Four to Score and what is their importance?

Lula is an ex-prostitute who works in the bonds office as a file clerk. On occasion, Lula goes out with Stephanie to help bring in FTAs. Lula dresses in a unique fashion, causing her inability to blend in with a crowd. Stephanie uses her a few times in this case to help track down Maxine. At one point, Stephanie calls Lula to give her a ride when her car is doused with gasoline. Inadvertently, this causes Lula's car to explode when she parks it next to Stephanie's car that is subsequently lit on fire by a carelessly discarded cigarette. Lula is not upset about this, however, because she leases the car and is able to replace it quickly.
